PORON® 4701 Series


PORON® 4701 Series for Custom Gasket and Seal Applications

PORON® 4701 Series products incorporate these highly reliable benefits:

PORON® 4701 Series

  • 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 UL94 HBF and MVSS 302.
  • Engineered polyurethane 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″ (0.43 mm to 12.7 mm)
