Teknor Apex Expands Low-Cost HFFR Jacket Compound Series


New General-Purpose Halguard® Products Include Two UL-94 V-0 Compounds with LOI up to 52% and a Low-Shrinkage Grade for Use in Fiber Optic Cable

PAWTUCKET, RI, U.S.A., April 20, 2015: New additions to a low-cost series of Halguard® halogen-free flame retardant (HFFR) compounds for general-purpose jacketing applications include two compounds with enhanced flame retardance and one that exhibits lower post-extrusion shrinkage, it was announced today by Teknor Apex Company, which will introduce the compounds at Interwire 2015 (Booth 212).

The new compounds cost less than premium compounds while entailing little compromise in performance properties (see table). Teknor Apex recommends them for cable used in subway, mass transit, cell tower, data center and infrastructure applications, as well as internal wiring in electrical and electronic equipment. The grades include:

Halguard 58610 and 58615.  These 53 Shore D compounds have UL-94 vertical burn ratings of V-0 for 1/16 in. (1.59 mm) thick specimens, and oxygen indices of 52 and 45%, respectively. Both enable passing the UL-1685 FT-4 and UL-1666 riser flame tests for more complex cable constructions.

Halguard 58620. This 54 Shore D compound provides the low level of post-extrusion shrinkage that is important for fiber optic cable applications and enables passing the UL-1685 flame test.

The new compounds follow last year’s introduction of the first compounds in the low-cost HFFR series, Halguard 58600 and 58605.

“Teknor Apex developed Halguard 58610, 58615, and 58620 to address specific needs reported to us by customers following the introduction of 58600 and 58605 grades,” said Mike Patel, director of marketing and business development for the Vinyl Division of Teknor Apex. “All five compounds meet the property requirements of general-purpose jacketing applications while costing less than other Halguard compounds or competing HFFR products.”
