ISOLOSS™ LS High Density Shock Absorbing Foams

ISOLOSS™ LS high density, fine-celled, polyurethane foam products are extremely lightweight, flexible, durable, and resilient, offering unique combinations of design features for difficult mechanical energy control problems. ISOLOSS™ LS foams are a Poron equivalent and display very low compression set and exceptional resistance to collapse, as well as good impact and vibration absorption. These high impact foams also exhibit excellent dimensional stability and low outgassing, with rigid thickness tolerances. 

ISOLOSS™ LS high density foam products are a direct Poron alternative and are perfect for managing difficult tolerances and mount problems from medical equipment, to gaskets and mounts. ISOLOSS™ LS absorbing foams provide excellent shock control and cushioning, yet are durable enough for gasketing, padding and sealing applications.

Advantages of High-Density Polyurethane Damping Foam

HD ISOLOSS™ LS absorbing foam products are direct Poron substitutes and offer a broad range of beneficial qualities that allow them to be used for numerous applications. Additionally, LS high impact foams are manufactured across several densities and thicknesses to ensure a tailored solution for any application. ISOLOSS™ polyurethane foam beneficial qualities include:
  • Low compression set
  • High durability
  • Broad operating temperature range [-40°F (-40°C) to 225°F (107.2°C)]
  • Multiple densities
  • Excellent rebound characteristics
  • Good chemical stability
  • Minimal outgassing
  • Excellent internal strength

Durable Damping Foam with Low Compression Set 

ISOLOSS™ LS foams often have superior individual attributes, such as compression set. A low compression set value indicates that the foam will constantly return to its original thickness after repeated or continuous compression, ensuring predictable performance through countless operating cycles.

ISOLOSS™ LS Foam Applications

Manufactured as a Poron equivalent, ISOLOSS™ LS foams micro-cellular foams provide resilient impact and vibration absorption and can be easily compressed for sealing applications. These polyurethane foams are ideal for managing difficult tolerances and mount problems. Additional ISOLOSS™ HD applications include:
  • Post and air seals
  • Enclosure and component mounting
  • Securing medical equipment
  • Gap filling with constant back pressure
  • Vibration damping & shock absorbing in electronic devices
  • Gasketing & gap filling
