Where Concepts Become Custom Solutions


American Flexible is highly regarded as a Preferred Converter for Rogers Corporation. We are very knowledgeable with both the PORON® Urethane and BISCO® Silicone product lines.

Various types of open cell urethane materials, custom manufactured and die cut by American Flexible Products.PORON® is an open cell microcellular urethane foam. It offers a broad range of design solutions for gasketing, sealing, vibration and sound dampening and energy absorption. Low compression set and low outgassing features make these high performance foams ideal for applications in communications, automotive, electronic, and other industrial devices.

PORON® products offer the following valuable benefits:

  • Outstanding 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.
  • Formulations offering a wide modulus range – 2-90 psi @ 25% deflection – allowing greater design flexibility.
  • Good chemical resistance
  • Easy to fabricate, cuts cleanly and bonds to a wide range of adhesives
  • Broad range of formulas and thicknesses from 0.012″ to 0.500″ (0.43mm to 12.7mm)
