Material Notes:
Very soft, easily compressed for use where flexibility is a key requirement.  Standard available  thickness range from 0.021"Features and Benefits of PORON Products: 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 resistanceEasy to fabricate, die-cuts cleanly and works with a broad range of adhesivesBroad range of formulas and thicknesses from 0.012" to 0.500" (0.43mm to 12.7mm)Applications:
