Poron 4701 Urethane Foams Gaskets

PORON® Urethane 4701 Foams for Gaskets and Dust Seals

  • Poron Sponge GasketsPORON 4701 urethane foam gaskets offer excellent compression set resistance which enables durable, long-term performance for gasketing, sealing, and cushioning.
  • PORON 4701 urethane sponge gaskets also provide low-outgassing and non-fogging, containing no plasticizers or residual chemicals to contaminate the device. PORON 4701 does not become brittle and crumble, and is non-corrosive to metal.
  • PORON 4701 foams are inherently flame retardant without the use of additives.
    • Many Rogers Poron grades meet UL flammability requirements HBF and MVSS 302.
  • Engineered urethane formulations offering a wide modulus range - 2-90 psi @ 25% deflection.
  • PORON 4701 foams provide good chemical resistance.
  • PORON is easy to fabricate, die-cuts cleanly and works with many adhesives.
  • Broad range of formulas and thicknesses from 0.012" to 0.500" (0.43mm to 12.7mm).
  • Rogers 4701 foams make excellent compression set resistant gaskets and dust seals.
