Softer, more compressible PORON® Cellular Urethanes are suited for sealing and gasketing applications such as handheld electronics that require low closure force Through a unique manufacturing process, PORON cellular urethanes can be cast to tight tolerances and in precise variations of firmness and internal strength. These materials are supplied in thickness from 0.012" to 0.500" (0.43mm to 12.7mm) and are easily die cut and fabricated to shape. Many PORON urethanes are conformable and thin for space constrained applications.
KEY FEATURES / BENEFITS
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.
Excellent performance over broad temperature range (-40oC to 90oC).
Good chemical resistance.
Easy to fabricate, die-cuts cleanly, and readily accepts adhesive without surface preparation. Available in a variety of colors.
