TPE Compound meets criteria

01 August 2007

Teknor Apex Company has announced that a new Elexar thermoplastic elastomer (TPE) compound meets stringent UL criteria for flame retardance, while providing the rubber-like flexibility and toughness required over a wide temperature range for flexible cord and industrial cable. The Thermoplastic Elastomer Division will introduce the new compound, designated Elexar EL-1392B, at IWCS / Focus (Booth 225).

The RoHS-compliant Elexar EL-1392B styrenic block copolymer TPE compound can be used in insulation, jacketing, and moulded plugs and connectors. It meets flame test requirements specified in UL 94 V-0 for thicknesses of 0.06 in. (1.5 mm), passes the VW-1 vertical flame test per Method 1080 per UL 1581 as both insulation and jacket, has an oxygen index of 28%, and exhibits no dripping when burned. The compound has a UL 1581 continuous use rating of 105ºC. Wires with both insulation and jacketing made of Elexar EL-1392B have passed seven-day oil-resistance tests at 60ºC.

“The enhanced flame performance of Elexar EL-1392B is achieved without use of polybrominated diphenyl ether (PBDE) flame retardant, ensuring that the compound will remain compliant regardless of possible future restrictions on deca-BDE use,” said Phil Scadding, wire and cable market manager. “Teknor Apex is prepared to supply identical formulations of this product worldwide, drawing on production facilities in the US, Europe, Singapore, and China.”

Recommended applications for the new TPE include cable and connector products for outdoor devices, power tools, appliances, industrial robots, welding equipment, and entertainment audio and lighting systems.
