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 K30 foams are soft, conformable, low deflection, urethane foams offering excellent compression set resistance and low out-gassing that exceeds fogging requirements. K30 is ideal for open/close applications.FEATURES/BENEFITS:Excellent compression set resistanceHighly resilient (will not collapse)Dissipates stressesResistant to moisture and most chemicalsConformable and flexible even in extreme environmental conditionsEasy to achieve intricate die-cut partsAggressive acrylic adhesive (optional) facilitates assemblyAvailable cast on to polyester film for stability and low deformationTypical Applications: Cellular telephones, electrical enclosures, electronic gasketing, vibration damping, cushioning, acoustical control, bumpers, instrument panels, spacers.Specification Notes: Passes Fogging Test SAE-J 1756, 3 hrs. at 212°F (100°C). All data based on a 0.045 inch test sample.(Available in multiple thicknesses.) Information provided by Saint Gobain Performance Products.
