Demanding Applications Require Uncompromising Material Solutions

Whether your application is for gasketing, cushioning, sealing, vibration management, or acoustics control – ISOLOSS™ LS Polyurethane Foams provide an all-purpose solution across many industries. ISOLOSS™ LS Foams are microcellular open-cell polyurethane foams that are soft, highly conformable, and spring-like to keep components in place.


Low Compression Set (<1% at 73°F)

The foam rebounds to maintain the same fit, form, and function throughout the product’s lifecycle (ASTM D1667).

Durable

Highly shock absorbent, flammability (UL94 HBF), and chemical resistant foams provide strength and longevity in extreme environments and temperature (-40ºC to 107°C)

Variety of Densities and Thicknesses

Available in 4 densities 10, 15, 20, and 25 lb/ft³. Fill various gap sizes with 8 thicknesses between 1/32″ to 1/2″.

Energy Control
