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 K40 series is a medium deflection urethane foam with minimal compression set. As with the K30, this series also offers low out-gassing and exceeds fogging requirements.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: UL Testing (JMST2) UL 50 and UL 508 File MH26338; Passes Fogging Test SAE-J 1756, 3 hrs. at 212°F (100°C). All data based on a 0.015 inch test sample. Information provided by Saint Gobain Performance Products.
