Silicone is gaining wider use in both solid and foam for its high temperature capabilities and excellent UV and weathering resistance. It can also be provided in FDA grade for use in contact with food. Microcellular urethane (Poron) is finding more applications in door seals for equipment boxes for its very low compression set.
Gardico can supply both materials with PSA added and plain.

An inventory item for every application includes natural and synthetic rubbers, sponge and foam, compressed sheet, cork materials, treated vegetable fiber, felt, high-temperature fabrics, mechanical packing and O-ring cord and O-rings.
