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
