Rogers Corporation Poron® 4701-30-25 Urethane Foam, Very Soft
Categories:	Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane Foam, Unreinforced
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 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) Applications:Communications Automotive Electronics Other industrial equipment and devices Information provided by Rogers Corporation.
