Elastomers for Noise and Vibration Control, Shock Protection and Ergonomics (manufactured by EAR)/
ISOLOSS® LS Foams

ISOLOSS® LS materials are finecelled, low compression-set, high density polyurethane foams, offering unique combinations of design features for difficult mechanical energy control problems. ISOLOSS® LS products exhibit very low compression set and excellent resistance to collapse as well as good shock absorption and vibration isolation performance.

ISOLOSS® LS foams are easily and cleanly die cut, and can be fabricated with various facings and combinations of pressure sensitive adhesives(PSAs). PSA backings simplify parts installation and reduce products assembly costs. ISOLOSS® LS foams provide excellent shock control and cushioning, yet are durable enough for gasketing, padding and sealing applications
  • Gasket - ISOLOSS® LS materials meet the gasket and seal requirements of UL50, 508 and 514B.
  • Vibration Isolation - Lightweight isolation applications take advantage of the foams’ low stiffness, high strength and controlled compression characteristics.
  • Shock Protection - Good durability, resilience and high energy absorption make the foams ideal for cushioning and shock applications, in plain form or laminated to fabrics, scrims or other facings.

Features

  • Low compression set.
  • High energy absorption.
  • Effective vibration isolation.
  • Low outgassing
  • High internal strength.
  • Chemical resistance.
  • Flame resistance.
  • Wide range of thickness and densities.
