Teknor Apex: TPE Compounds for Appliance Wire

Three Elexar styrenic thermoplastic elastomer compounds rated for continuous service at 125ÞC in appliance wire provide chemical resistance, low-temperature flexibility and a range of mechanical and flame properties, according to the Thermoplastic Elastomer Division of Teknor Apex. Two grades with high tensile strength, Elexar 8614 and 8623, are non-brominated and have UL-94 flame resistance ratings of V-1 and HB, respectively. These products enable users to meet recent European demands for elimination of bromine compounds. Brominated Elexar 8730 compound has a V-1 rating and is the softest grade. An accompanying table provides data on all three grades and illustrates performance advantages over thermoplastic vulcanizate (TPV) elastomers typically used in appliance wire. “Besides serving as non-plasticised alternatives to PVC in appliance wire, Elexar TPEs provide greater chemical resistance and low-temperature flexibility than thermoplastic olefin elastomers and cost less than urethane and polyester based TPEs,” said John Macaluso, Wire and Cable Market Manager for TPEs.
