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.

Your Go-To Gasketing Solution

ISOLOSS™ LS Polyurethane Foam is UL gasket & sealing rated for applications that are exposed to harsh environments, liquids, and gases. The open-cell foam rebounds to maintain the same fit, form, and function throughout the product's lifecycle. The foam pairs well with your favorite 3M™ Laminating Adhesives for a custom fit.

  • Touch screen/LCD display gasket
  • Small appliance motor gasket
  • Dishwasher vent gasket
  • Badge gasketing
  • Utility door gasket
  • Light filtering gasket

Light-duty Sealing

Secure the seal with a foam that lasts longer in demanding applications. ISOLOSS™ LS Polyurethane Foam rebounds and holds shape under stress. The flame and chemical resistance provide strength and longevity in harsh conditions. The foam is easy to compress and creates a light-duty seal with 25-30% compression.

  • Touch screen/LCD display gasket
  • Small appliance motor gasket
  • Dishwasher vent gasket
  • Badge gasket
  • Office chair gasket
  • Light filtering gasket

Soft and Supportive Foam

ISOLOSS™ LS Polyurethane Foams softness allows the foam to conform to the design and cushion the parts. ISOLOSS™ LS Foam is available in 10, 15, 20, and 25 lb/ft3 densities to provide varying levels of support. The spring-like foam rebounds quickly – the fast recovery helps reset mechanisms to their original state, even on uneven surfaces.

  • Printer paper tray cushioning
  • Part/component cushioning
  • Cushioning for tolerance concerns
  • Office electronics
  • Automotive padding

Fills Gaps to Help Protect Equipment

ISOLOSS™ LS Polyurethane Foam is available in eight thicknesses from 1/32" to 1/2" to help fill a variety of gap sizes. In addition to gap filling, the soft foam conforms to the design to cushion parts and reduce noise and vibrations. Gap filling helps protect components from wear and tear and keeps parts in place to maintain performance.

  • HVAC system gap filling
  • Instrument panel gap filling
  • Industrial touch screen gap filling
  • Enclosure gap filling
  • Tolerance concern gap filling
  • Gap filling for noise reduction

Block the Shock. Isolate the Noise.

From sensitive electronics to earth-shaking heavy equipment, help protect critical equipment from impact, shock, and vibration. Noisy parts create wear and tear on equipment. ISOLOSS™ LS Polyurethane Foam is inherently damping with damping properties to help reduce noise and absorb impact. The foam is soft and can conform to uneven substrates to help reduce energy.

  • Small motor noise reduction
  • Panel vibration damping
  • Enclosure damping
  • Shock absorbing pad
  • Vibration damping pad
  • Impact absorption (drop)
  • Noise Vibration Harshness (NVH)
  • Buzz, squeak, and rattle (BSR)
