2/02 PAWTUCKET, RHODE ISLAND, U.S.A., February 25, 2002: Three Elexar (R) styrenic thermoplastic elastomer compounds rated for continuous service at 125 °C in appliance wire provide chemical resistance, low-temperature flexibility, and a range of mechanical and flame properties, the Thermoplastic Elastomer Division of Teknor Apex announced today.
Three TPE Compounds for Appliance Wire Provide Range of Options in Softness, Strength, and Flame Resistance
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.
"Besides serving as non-plasticized alternatives to PVC in appliance wire, Elexar TPEs provide greater chemical resistance and low-temperature flexibility than thermoplastic olefin (TPO) elastomers and cost less than urethane- and polyester-based TPEs," said John E. Macaluso, Wire and Cable Market Manager for TPEs. "Elexar compounds also exhibit physical properties equal to or better than those of commercially available flame-retardant compounds based on TPV elastomers and have the added advantage of being processable without predrying."
All three products are UL-listed for "60 °C Oil Resistant" applications. Aged for seven days in ASTM #2 oil at a temperature of 60 °C, the Elexar 8614 grade retained 93% of its tensile strength and 100% of its elongation.
