Flexalloy® 89504-90 Compounds from Teknor Apex Provide Low-Temperature Flexibility, Oil Resistance, UL Recognition for Many Uses, and Option to Pair with Flexalloy Jackets

PAWTUCKET, RI, U.S.A., March 8, 2019: Two PVC elastomer compounds for wire and cable insulation exhibit the enhanced performance required in diverse demanding applications while providing manufacturers with new options for versatility. Teknor Apex Company will feature the compounds at Interwire 2019 (Booth 305).

As thermoplastic elastomers, Flexalloy® 89504-90 and -90FR compounds provide greater low-temperature flexibility than standard PVC and more capability to withstand repeated flexure over a long working life. Both grades have Shore A hardness ratings of 90, are UL recognized for Oil I and II as insulation, and meet the requirements of the VW1 (UL 83) flame test. The FR grade provides a greater level of flame resistance and has UL recognition for meeting the 720 hour sunlight resistance test in all colors.

“Teknor Apex received dual UL recognition for Flexalloy 89504-90 products as both “PVC” and “elastomer” compounds, enabling them to be used for all cable types within UL 62 and many wet-rated applications under UL 83,” said David Braun, wire and cable industry manager for the Vinyl Division of Teknor Apex. “In cases where these insulation compounds are matched with our extensive line of Flexalloy jacket materials, manufacturers can use Teknor Apex as a single cable compound source.”

Recommended applications for Flexalloy 89504-90 compounds include factory automation and robotics cables; control and instrumentation cables (TC, PLTC, ITC and CIC); custom appliance wires; flexible cords (UL 62), including electric vehicle charging cables; portable power cables such as those used on construction sites; stage lighting cables; and welding cables.
