PORON® Microcellular Urethanes for Gasketing and Sealing

Providing Solutions For... communications automotive electronics other industrial equipment and devices PORON products incorporate these highly reliable benefits: Excellent compression set resistance which enables durable, long-term performance for gasketing, sealing, and cushioning. Low-outgassing and non-fogging, containing no plasticizers or residual chemicals to contaminate the device. The material will not become brittle and crumble and is non-corrosive to metal. Inherently flame retardant without the use of additives. Many of the materials meet flammability requirements of UL HBF and MVSS 302. Engineered urethane formulations offering a wide modulus range - 2-90 psi @ 25% deflection – for more design versatility requirements. Good chemical resistance Easy to fabricate, die-cuts cleanly and works with a broad range of adhesives Broad range of formulas and thicknesses from 0.012" to 0.500" (0.43mm to 12.7mm) Rogers Sales, technical service, customer service – around the world Contact our expert sales, technical service and customer service personnel in the Americas, Europe and Asia.
