Saint-Gobain Korel® K20 Very Soft Micro-cellular Polyurethane Foam
Categories: Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane Foam, Unreinforced

Material Notes: Description: The Korel® series micro-cellular polyurethane foams are offered in a broad range of properties, making them ideal for a variety of gasketing and energy absorption needs. Korel® microcellular foams are categorized by degree of deflection force. By varying the modulus and density, Saint Gobain Performance Plastics has developed this series of materials that meets the demands of design engineers today. All Korel fians are available with an aggressive acrylic adhesive on one side to facilitate placement. Korel K20 foams are very soft and highly conformable, with a very low force to deflect. Korel K20 is recommended for closure of irregular surfaces or flexible materials.
FEATURES/BENEFITS:
  • Excellent compression set resistance
  • Highly resilient (will not collapse)
  • Dissipates stresses
  • Resistant to moisture and most chemicals
  • Conformable and flexible even in extreme environmental conditions
  • Easy to achieve intricate die-cut parts
  • Aggressive acrylic adhesive (optional) facilitates assembly
  • Available cast on to polyester film for stability and low deformation
Typical Applications: Cellular telephones, electrical enclosures, electronic gasketing, vibration damping, cushioning, acoustical control, bumpers, instrument panels, spacers.
Specification Notes: UL Testing (JMST2) UL 50 and UL 508 File MH26338. All data based on a 0.14 inch test sample.(Available in multiple thicknesses.)
