Features and Benefits of PORON® Microcellular Polyurethanes

PORON® Cellular Polyurethane 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 market segments.

PORON Polyurethanes are flexible, high density, microcellular products that offer design engineers many outstanding features. PORON foams maintain excellent resistance to compression set, exhibit high resiliency, provide good vibration damping and impact absorption. Parts made from PORON foams continue to perform after constant
and repeated deflection. Components will not loosen and gasketing integrity will be maintained.

KEY FEATURES / BENEFITS

Excellent compression set resistance for durable,long-term performance.

Low-outgassing prevents component fogging,corrosion, and embrittlement.

Meets several flammability requirements including MVSS 302 and UL HBF.

Available in many densities, thicknesses, and surface finishes, providing wide design latitude.

Excellent performance over a broad temperature range (-40oC to 90oC).

Good chemical resistance.

Quality manufacturing provides consistent easy-to-process roll goods.
