micro-cellular polyurethane foams offer a broad range of design advantages for those engineers who are involved with gasketing, sealing, energy absorbtion or
have excellent compression-set resistance and high resilience, providing a gasketing seal that won't break down over extended use.
foams are conformable and flexible even under extreme environmental conditions.

is significantly less expensive than silicone and can replace silicone in many applications in which a low-compression set, low out-gassing, and flame retardant material is required.
foams are exceptionally easy to die-cut or water-jet cut. The surface of

Standard Products and Adhesive Backings (Optional)
Our general purpose Poron® Foam (Microcellular Polyurethane) is available in four grades of compressibility, determined by compression deflection.
is very soft, easily compressed and often used where flexibility is a key requirement.
is soft and good for use in a wide variety of applications.
, firm grade, is often used in applications where there is a substantial amount of energy to be absorbed.
is very firm like solid rubber and can withstand much greater compressive force than ordinary foam. Two additional Poron® Foams are now available from Auburn.
is extra soft, slow rebound foam with the lowest closure force of any Poron®.
has a closed-cell foam structure and is designed to provide enhanced sealability. Vacuum-enclosure applications, for example, will require this material.
All Poron® Foam is now available with or without adhesive.
Auburn's adhesive backings can be applied to one or both sides
Ordering Information & Special Orders
» 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
@ 25% deflection – for more design versatility requirements.
» Excellent performance over broad temperature range (-40°C to 90°C) with
good chemical resistance.
» Easy to fabricate, die-cuts cleanly, and readily accepts adhesive without
surface preparation. Available in a variety of colors.
Auburn can die-cut, water-jet cut, slit to width, laminate and apply adhesive
to all Poron® Foam
products. Auburn can supply Poron®
sheets, rolls or custom parts. All Poron® Foams
can be supplied either plain (no adhesive) or with an
applied to one or both sides. For additional technical assistance,
