Original Press Release:
New TPE Provides Enhanced Flame Retardance for Flexible Core and Industrial Wire and Cable
Teknor Apex Will Introduce Elexar® EL-1392B Compound at IWCS / Focus for Insulation and Jacketing Applications, including Outdoor and Oil-Resistant Products
PAWTUCKET, RI, July 27, 2007: 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, it was announced today by Teknor Apex Company. 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 molded 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 105 deg. C. Wires with both insulation and jacketing made of Elexar EL-1392B have passed 7-day oil-resistance tests at 60 deg. C.
"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 U.S., 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.
Property data on Elexar EL-1392B appear in the accompanying table.
The Thermoplastic Elastomer Division of TEKNOR APEX COMPANY is the most diversified custom compounder of TPEs and supplies three product lines for wire and cable: Elexar® styrenic block copolymer compounds combine superior electrical properties with flexibility and toughness. With brittle points as low as -100°C, and continuous operating temperatures UL rated for 105°C and 125°C, they are excellent for wide temperature range applications. Telcar® thermoplastic olefins (TPOs) are polyolefin/rubber blends that provide rubber-like feel and physical properties, plus resistance to heat aging and ozone. They are available in flame-retardant grades for both fiber optic and copper cable applications. Uniprene® thermoplastic vulcanizates (TPVs) exhibit a wide service temperature range (-60°C to +135°C). They perform, appear, and feel similar to vulcanized rubber, and are available in hardnesses of Shore 45A to 50D. UV resistant grades are standard and FR grades are available for insulation and jackets. NSF and USP Class VI compounds are also available for regulated and medical applications.
