    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.
