What is Poron Foam?

Poron is a microcellular polyurethane foam known for its outstanding durability and resistance to compression set.

Unlike many foams that degrade or lose performance over time, Poron maintains its thickness, resilience, and sealing integrity under continuous pressure and stress.

With excellent energy absorption and impact resistance, Poron is widely used for gasketing, cushioning, and vibration management. Its uniform microcellular structure also delivers consistent performance across a broad range of applications, from electronics to transportation.
