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 low out gassing and flame retardant (UL-Listed).
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
is smooth, cosmetically appealing and ideal for having adhesives applied. Typical applications for
include; cellular telephone gasketing, electrical enclosures, electronic gasketing, vibration damping, cushioning pads, acoustical control gasketing and automotive gasketing.
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,
