PORON® Cellular Urethane
PORON® Cellular Urethane foams offer a broad range of design
solutions for gasketing, sealing and energy absorption. Low compression
set and low outgassing features, make these foams ideal for applications
in telecommunications, automotive, electronic, and other industrial
devices.
PORON urethanes: flexible, high density, microcellular products,
offer design engineers many outstanding features. PORON products
maintain excellent resistance to compression set (collapse), exhibit
high resiliency, good vibration damping and impact absorption. Parts
made from PORON urethanes continue to perform after constant and
repeated deflection. Components will not loosen, and gasketing integrity
will be maintained.
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 Temperature (-40oC
to 90oC).
Good Chemical Resistance
Easy to fabricate, die-cuts cleanly, and readily accepts adhesive
without surface preparation. Available in Colors
