Material Notes:
KEYFLEX resins, thermoplastic elastomers divided by polyester and polyolefin type, have been developed by LG`s own polymerization and compounding technology. They display the flexibility of rubber and the strength of engineering plastics. In additions, they offer very good thermal stability, chemical resistance and weather resistance. KEYFLEX resins can be widely accepted as the replacement of thermoset rubbers.Characterization: High impact strengthLow specific gravityExcellent resistance to chemicals and weatheringGood electrical propertiesVarious hardness grades (soft, semi-soft, and hard)ColorabilityRecyclabilityApplications: Automotive: Exterior: Bumper, air spoiler, mud guard, trim, side moldingInterior: Head liner, instrument panel skin, glass sealing, door trim skinOthers: Air intake hose, air duct, lamp packing, weather stripping, handle gasket, boots dustOthers: Hose, packing, phone foots, gasket, insulation sheet (water protection sheet etc.), racket grip, booster cable, pump cableInformation Provided by LG Chem
