Proposed wire and cable products incorporating
high-performance Flexible Noryl resins, now
need to undergo only short-term ageing testing
vs. a 150 day long-term ageing test, speeding
time to market. This is because Flexible Noryl
grade developed by GE in 2005 has been now accepted
by Underwriter Laboratory as cable coating and
is governed by UL1581 standard for cable with
temperature rating of 105 degree C. The new
GE materials have already proven themselves
in the automotive and consumer electronics industries,
and, with this new UL listing, are poised for
rapid growth in appliance wiring applications.
The UL758 safety standard is used by UL to
evaluate wire and cable applications and assign
successful constructions an AWM Style number
and descriptive style page that provides a set
of criteria for an AWM construction that other
manufacturers must adhere to. Since Flexible
Noryl resin was listed, approximately 30 new
AWM Style Pages have been approved for various
products that incorporate the GE materials.
Most of these applications, including computer
cable, hook-up wire, flat ribbon cable, use
Flexible Noryl resins as a replacement for PVC
wire coatings to meet end-customer requirements
for non-halogenated flame retardants. The material
provides excellent performance properties such
as excellent temperature and flammability, better
abrasion resistance than cross-linked polyethylene
(XLPE), excellent chemical resistance, and lower
specific gravity (1.03) than either PVC or PE.
For wire and cable manufacturers, this polymer
also offers easy processing and faster throughput,
as it does not require cross-linking. Flexible
Noryl is an excellent material candidate for
thin-wall and ultra-thin-wall coating that can
significantly reduce weight and mass.
Flexible Noryl resins provide flame-retardant
properties capable of meeting UL1581-VW1 performance,
one of the most stringent global requirements
for consumer electronics. As a replacement for
PVC, which can leach phthalates (plasticizers)
into the environment and form dioxins when burned,
the Flexible Noryl resin portfolio of 10 grades
complies with the European Union's Restriction
of Hazardous Substances (RoHS) standard governing
specific heavy metals and certain brominated
FR additives. Flexible Noryl resins also help
customers comply with Waste Electrical and Electronic
Equipment (WEEE) requirements by avoiding an
additional waste stream from PVC that can add
to recycling costs.
