• How do I get a custom foam gasket made? Foam Gaskets

    Send a converter your drawing plus the six details at the top of this guide: geometry, sealing job, compression, material or constraints, adhesive backing, and quantities with any compliance needs. A good converter will confirm the material choice, prototype without tooling if the design might change, and move you onto production tooling when it is stable.

  • Can foam gaskets be supplied self-adhesive? Foam Gaskets

    Yes, most foam gaskets are supplied with a pressure-sensitive adhesive on one face and a peel-off liner, turning fitting into a peel-and-stick operation. The adhesive is chosen for the surface it bonds to, and parts can be presented individually, on sheets, or kiss-cut on a continuous roll for production lines.

  • What is compression set and why does it matter? Foam Gaskets

    Compression set is the permanent thickness a foam loses after being held compressed. A gasket seals by pushing back against the joint; a material with high compression set stops pushing back over time and the seal fails, even though the gasket looks intact. For permanently clamped gaskets it is the most important number on the datasheet.

  • What is the difference between open-cell and closed-cell foam gaskets? Foam Gaskets

    Closed-cell foam has sealed gas pockets, so it blocks water and air and compresses like a spring: the default for weather sealing. Open-cell foam has interconnected cells, so it breathes and conforms extremely well: better for dust sealing, cushioning and joints with large irregularities, but not for immersion.

  • What is the best gasket material? Foam Gaskets

    There is no universal best, only best for the environment. Closed-cell EPDM leads for outdoor and water sealing, silicone sponge for temperature extremes, PVC/nitrile for oils and fuels, and polyurethane foams like Poron for thin gaskets under permanent compression. The material follows from what the gasket must survive.

  • What is a foam gasket? Foam Gaskets

    A foam gasket is a compressible sealing component cut from cellular rubber or plastic foam, fitted between two surfaces to seal against water, dust, air, light or noise. Unlike solid rubber gaskets, foam gaskets seal at low clamping forces, which suits enclosures, panels and assemblies that cannot be bolted down hard.

  • What quantities can you support? Medical

    From prototype runs and samples through to scaled, high-volume production. Our in-house converting and quality systems, certified to ISO 9001:2015 and IATF 16949:2016, keep parts consistent as volumes grow.

  • Can you help before we have a final design? Medical

    Yes. We offer engineering support, material selection guidance, design and prototyping, and testing and validation. Bring us the application or a concept drawing and we will help identify a practical converting route before production.

  • What formats can you supply converted parts in? Medical

    We die-cut adhesives, tapes, foams and films to your drawing, supplying parts as individual die-cuts, kiss-cut sheets or rolls, including formats compatible with automated pick-and-place and roll-to-roll assembly.

  • Can you bond low-surface-energy plastics such as PP, PE, TPU and PEEK? Medical

    Yes. 3M Thin Bonding and VHB tape families include formulations engineered for low-surface-energy and difficult engineering plastics. We select and convert the right adhesive for your substrate combination.

  • Will bonded assemblies withstand repeated cleaning and disinfection? Medical

    Many 3M adhesive constructions are designed to resist moisture and common disinfectants used in clinical environments. Suitability depends on the exact material and cleaning regime, so we recommend testing against your protocol. We can advise on material selection and support validation.

  • Can adhesive tapes really replace screws and welds in medical furniture and equipment? Medical

    In many applications, yes. 3M VHB and pressure-sensitive adhesive tapes form strong structural and semi-structural bonds across metal, plastic, glass and composites. They remove dirt-collection points, reduce assembly time and allow cleaner, more ergonomic designs. We help you validate the bond for your specific application before committing to production.

  • Does aluminium foil shield EMI? EMI Shielding

    Conductive metals like aluminium do reflect electric-field EMI, which is why foil tapes exist. But household foil has no conductive adhesive, cannot maintain grounding contact across joints, and does almost nothing against low-frequency magnetic fields. Engineered shielding tapes and gaskets solve the contact and continuity problems that determine real-world performance.

  • How do you use EMI shielding tape? EMI Shielding

    Clean both surfaces, apply the tape or die-cut part across the joint or onto the grounding point, and apply firm pressure so the conductive adhesive makes contact. For repeatable results in production, tapes are usually supplied as die-cut or kiss-cut parts sized to the joint rather than cut from a roll by hand.

  • Why is EMI shielding important? EMI Shielding

    Unshielded interference degrades the signal-to-noise ratio in electronic systems, causing data errors, sensor misreads and intermittent faults, and it can push a product over the legal emissions limits it must meet for CE or UKCA marking. As devices get denser and switching frequencies climb, shielding is now designed in rather than retrofitted.

  • What is the difference between EMI and RFI? EMI Shielding

    RFI is a subset of EMI. EMI covers all electromagnetic disturbance, from low-frequency magnetic fields to microwave-band noise; RFI refers specifically to interference in the radio frequency range. In shielding practice the terms are used almost interchangeably, which is why materials are usually badged EMI/RFI.

  • How does EMI shielding work? EMI Shielding

    Conductive shields work like a Faraday cage: incident electromagnetic energy induces currents in the conductive surface, which reflect and dissipate it instead of letting it reach the circuit. Absorbers work differently, converting electromagnetic energy to heat in magnetic particles. Effectiveness depends on conductivity, coverage and, above all, the continuity of the shield at seams and gaps.

  • What is EMI shielding? EMI Shielding

    EMI shielding is the use of conductive or magnetic materials to block, redirect or absorb electromagnetic interference so it cannot disrupt electronic circuits. In practice it means conductive gaskets, tapes, absorbers and coatings applied to enclosures, joints and components.

  • Can thermal tape be removed? Thermal Tape Selection

    Carrier-backed grades like the 3M 8926 series are designed to be reworkable during assembly. Transfer tapes (8805 to 8820) form a permanent bond; removal requires mechanical peeling and solvent cleaning of residue.

  • How do you apply thermal tape? Thermal Tape Selection

    Clean both surfaces with isopropyl alcohol, position the die-cut pad, and apply firm, even pressure with a roller or press. Full bond strength builds over about 72 hours, so avoid stressing the joint immediately after assembly.

3M™ Electrically Conductive Adhesive Tapes

  • What is the difference between XYZ-axis and Z-axis conductive tapes?

    XYZ-axis (isotropic) conductive tapes provide electrical conductivity through both the thickness of the tape (Z-axis) and across the surface plane (X and Y axes), making them ideal for general shielding and grounding. Z-axis (anisotropic) conductive tapes only allow electricity to flow vertically through the thickness of the tape, isolating adjacent closely-spaced traces without shorting them.

  • Do these conductive tapes require thermal curing to bond?

    No. 3M™ Electrically Conductive Tapes use advanced pressure-sensitive adhesives (PSAs). They achieve high-bond strength and reliable electrical contact instantly upon physical pressure at room temperature, eliminating the need for time-consuming thermal curing or specialised ovens.

  • Can conductive tapes be used on irregular or soft surfaces?

    Yes. Many tapes in the 3M range feature highly conformable foil or fabric backings (such as nonwoven scrims or woven threads). These backings allow the tape to easily flex, wrap around edges, and maintain consistent, reliable contact with both rigid, soft, or textured substrates.

  • How do 3M conductive tapes perform over long periods?

    These tapes are engineered for long-term environmental stability. They offer excellent resistance to oxidation, high temperatures, and moisture, ensuring that the electrical contact resistance remains low and grounding performance stays secure throughout the lifespan of the device.

  • What custom converting options does RGH offer for these tapes?

    As a precision converter, RGH can supply 3M conductive tapes custom-cut to your exact production requirements. We provide them in bespoke roll widths, strips, or precision die-cut parts on a removable liner, allowing for seamless integration and fast, waste-free application on your assembly line.

3M™ EMI Absorbers

  • What is the difference between an EMI absorber and an EMI shield?

    While EMI shields (like copper or aluminum foils) reflect electromagnetic energy to block it from passing through, EMI absorbers contain specialised magnetic particles that actually soak up the noise and convert it into negligible thermal energy. Absorbers are ideal for eliminating internal reflections and suppressing near-field noise within a closed device.

  • How do I choose the correct thickness for an EMI absorber?

    Absorbing performance is highly thickness-dependent. Thicker absorbers generally offer higher attenuation and work better at lower frequencies, whereas ultra-thin absorbers are optimised for high-frequency noise and tight spaces. Our technical team can help you select the exact thickness required to target your specific problem frequencies.

  • Can EMI absorbers be supplied with adhesive backing?

    Yes. We can convert EMI absorbers with an optional pressure-sensitive adhesive (PSA)—available in both conductive and nonconductive options. This allows for quick, reliable peel-and-stick application directly onto components, shields, or enclosures during production line assembly.

  • How does an EMI absorber improve antenna performance?

    When placed near internal antennas, absorbers suppress stray electromagnetic noise and crosstalk from nearby microprocessors or high-speed components. By cleaning up this background "noise," the absorber significantly improves the signal-to-noise ratio (SNR), leading to better wireless connectivity and device performance.

  • What custom shapes and formats can RGH provide?

    As a precision converter, RGH can supply EMI absorbers in rolls, sheets, strips, or custom die-cut parts tailored to the exact geometry of your electronic housing or internal components. This ensures a perfect fit for complex layouts and fast integration into your manufacturing process.

Thermal Tape Selection

Thermal Tape Selection

  • What is thermal tape used for?

    Thermal tape bonds heat-generating electronic components (LEDs, power ICs, sensors) to heat sinks, spreaders or housings while conducting heat across the joint. It replaces mechanical fasteners and separate thermal interface materials in one peel-and-stick step.

  • Does thermal tape actually work?

    Yes, within its design envelope. Filled acrylic tapes conduct 0.6 to 1.5 W/m·K, a 20 to 50 times improvement over the air gap they replace. For extreme heat loads with existing clamping, paste can outperform tape; where the tape must also hold the part, it is usually the better system choice.

  • Is thermal tape electrically conductive?

    No. Standard thermally conductive tapes use ceramic fillers that conduct heat but insulate electrically, with dielectric strengths of 15 to 26 kV/mm. 3M's 9876 heat spreading tape, built on a copper layer, is the exception; check before using it near live circuits.

  • Is Kapton (polyimide) tape thermally conductive?

    Not meaningfully. Standard polyimide tape is an electrical insulator with low thermal conductivity (roughly 0.2 W/m·K) and is used for masking and electrical insulation, not heat transfer. For thermal joints, use a purpose-filled thermally conductive tape.

  • How do you apply thermal tape?

    Clean both surfaces with isopropyl alcohol, position the die-cut pad, and apply firm, even pressure with a roller or press. Full bond strength builds over about 72 hours, so avoid stressing the joint immediately after assembly.

  • Can thermal tape be removed?

    Carrier-backed grades like the 3M 8926 series are designed to be reworkable during assembly. Transfer tapes (8805 to 8820) form a permanent bond; removal requires mechanical peeling and solvent cleaning of residue.

Thick Bonding

  • What makes 3M™ VHB™ Tape different from ordinary foam tape?

    Unlike standard foam tapes, 3M™ VHB™ Tape is made entirely of adhesive, not just coated on the surface. Its viscoelastic structure allows it to flow into surface textures and maintain strong, flexible bonds — even between materials like metal, glass, and plastic. It can also absorb stress and vibration, helping to create, attractive long-lasting joints by replacing unsightly screws, rivets and heavy welds.

  • What is the best way to prepare a surface before applying 3M™ VHB™ Tape?

    Proper surface preparation is key to a strong bond. Follow these simple steps:

    1. Clean the surface using VHB Surface Cleaner 50:50 mix of isopropyl alcohol (IPA) and water
    2. If dirt, oil, or past adhesive residue needs removing, use 3M™ Industrial Cleaner to remove the contaminent and then make a final wipe with 3M VHB Surface Cleaner (Very important)
    3. Some tricky surfaces, may benefit from a primer.

    NB - Always let the surface dry before applying the tape.

  • How do I apply 3M™ VHB™ Tape correctly?

    Here’s a quick guide:

    • Clean both surfaces to be bonded
    • Apply the tape evenly without stretching or trapping air bubbles.
    • Roll it down firmly with about 2 kg of pressure per cm² (a firm rub down with a dense rubber roller) to ensure full contact.
    • After joining the parts, initial 'handling strength' is normally achieved in 20 - 60 mins with full strength resulting in approx 72 hours at 15oC or above

    NB - Please refer to 3M Product Data sheets for full application guidelines.

  • Can 3M™ VHB™ Tapes handle outdoor or high-temperature use?

    Yes. 3M™ VHB™ Tapes are designed for indoor and outdoor environments, resisting moisture, UV, and temperature extremes. Different grades are available — for example:

    • GPH series for high heat (up to 230°C short-term).
    • LSE series for low surface energy plastics like PP or TPO.
    • 4910 Transparent series for glass and clear plastics.
  • Do I need special tools or equipment to use 3M™ VHB™ Tape?

    No special tools are needed for most applications. A clean 'lint free' cloth, roller, and some pressure are usually enough. For industrial applications, 3M also offers application tools and automated systems to make bonding even faster and more consistent.

  • What are the benefits of using thick bonding tapes like 3M™ VHB™?

    Thicker bonding tapes offer:

    • Gap filling and compensation for surface irregularities
    • Allowance for differential thermal expansion between disimilar materials
    • Even stress distribution over the bond area
    • Noise and vibration damping
    • A clean look with no visible screws or rivets
    • Weather and corrosion resistance
    • Simplified application over mechanical fixings

    NB: Refer to 3M Data sheets for more information

Thin Bonding Tapes

  • What materials will these thin tapes bond to?

    3M Thin Bonding Tapes adhere well to metals, glass, composites, painted surfaces, ABS, PC, and acrylics.

    Some versions have been modified to work on low surface energy (LSE) plastics such as Polypropylene and Polyethylene or powder coated paints.

    The use of 3M Primers can also be used to enhance performance.

  • How thin are the tapes available, and does thickness affect performance?

    Thin tapes (0.05mm to 0.3mm) are typically used when one or both bonded surfaces is flexible. This is because these tapes are pressure sensitive so good rub down pressure is needed to ensure a good bond is achieved.

    If both bonded surfaces are rigid, thin tapes may still be considered for small component parts; For larger areas or a longer bond line, thicker tapes (0.4mm to 2.3mm thick) will provide better surface to surface contact and therefore optimise bond performance.

  • What is the different between a double coated tape and an adhesive transfer tape?

    A double coated tape has a ‘carrier’ which can be made of tissue, polyester, PP or paper with a thin coating of adhesive on both sides; This ‘carrier’ enables the tape to be handled and processed easily; however, bond strength and temperature performance can be limited by the type of carrier.

    For ultimate bond performance Adhesive Transfer Tapes, which have no carrier are just a thin film of pressure sensitive adhesive (PSA); as the tape has no ‘carrier’ the adhesive ‘flows’ better into the surface whilst also typically achieving higher temperature performance.

    RGH are happy to give guidance on which is most suitable for any given application.

  • Can they be used outdoors or in automotive/industrial environments?

    Yes, 3M Thin Bonding Tapes have been used for automotive interiors and for outside environments; they are typically acrylic based adhesives which can resist UV, solvents, humidity and high and low temperatures. Its important to consider all aspects of any given application so please contact us should you’d further guidance on product selection.

  • What roll sizes, formats, and die-cutting options are available?

    RGH can supply these materials in various roll widths (wide or narrow), vary roll lengths or provide customised shapes (ie: finished die cut parts) to customer specifications; we can also laminate these materials to third party materials prior to converting into the desired shape.

    Please refer to RGH Capabilities page or make an enquiry.
