Rogers Corporation Poron® 4701-41-30 Urethane Foam, Soft, Enhanced Sealability
Categories: Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane Foam, Unreinforced

Material Notes: Soft, enhanced sealability material offering greater closed-cell content for demanding vacuum sealing applications or low closure-force requirements.  Standard available thickness range from 0.031" to 0.500" (0.79 mm to 12.7 mm).

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
