ISOLOSS™ LS Polyurethane Foam - All-Purpose Cushioning Foam
Block the shock. Secure the seal. Isolate the noise.
Demanding applications require uncompromising material solutions. Whether the application is for gasketing, cushioning, sealing, vibration management, or energy control — ISOLOSS™ LS Polyurethane Foams provide an all-purpose solution across many industries. ISOLOSS™ LS Foams are microcellular open-cell polyurethane foams with a low compression set to maintain the component's original fit, form, and function throughout the product's lifecycle. The highly shock absorbent, and flame and chemical resistant foams provide strength and longevity in extreme environments with a wide temperature range. These soft and spring-like foams are available in multiple densities, stiffnesses, and thicknesses to fill various gap sizes and conform to designs.
