Enhanced flame retardance and low-shrinking grades

New additions to a low-cost series of Halguard ® halogen-free flame retardant (HFFR) compounds for general-purpose jacketing applications include two compounds from Teknor Apex with enhanced flame retardance and one that exhibits lower post-extrusion shrinkage. The new compounds cost less than premium compounds while entailing little compromise in performance properties. Teknor Apex recommends them for cable used in subway, mass transit, cell tower, data centre 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" (1.59mm) thick specimens, and oxygen indices of 52 and 45 per cent, 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 fibre optic cable applications, and enables passing the UL-1685 flame test Teknor Apex – USA Website : www.teknorapex.com
