PORON® Microcellular Urethanes for Gasketing and Sealing

PORON® flexible, high-density, microcellular urethane foams provide excellent solutions for: communications automotive electronic other industrial 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. Excellent performance over broad temperature range (-40oC to 90oC). Good chemical resistance Gasketing integrity, without loosening Easy to fabricate, die-cuts cleanly, and readily accepts adhesive without surface Ability to withstand constant, repeated deflection Unique manufacturing process enables, PORON microcellular urethanes to be cast to tight tolerances and in precise variations of firmness and internal strength Supplied in thickness from 0.012" to 0.500" (0.43mm to 12.7mm) Many PORON urethanes are conformable and thin for space constrained applications available in a variety of colors Rogers PORON Quality and Environmental Assurance AS9100 Aerospace Quality Certification PORON® ReGen Materials: Reduce, Reuse, and Recycle Without Sacrificing Performance 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.
