UL has recognised seven Halguard® low-smoke, halogen-free flame retardant
(LS-HFFR) compounds for wire and cable as “halogen-free” in accordance with a
new assessment programme, it has been announced by the vinyl division of
Teknor Apex. Also listed as in compliance are 14 halogen-free colour
concentrates from the company’s colour division.
Inaugurated last year, the UL programme certifies cable components as
halogen-free in accordance with combustion tests to determine acid gas content,
acidity and conductivity. Compliance is listed in UL AATJ2.
The seven Halguard LS-HFFR products listed include:
● Five high-performance 58000-58300 Series compounds. Halguard LS-HFFR
compounds in these series exhibit a higher level of flame retardance than
other high-performance
HFFR materials without
compromising physical or
electrical properties. They
are recommended for data
centre cables, control
cables, energy cables, and
other demanding applic-
ations where low smoke
generation and minimal
flame spread are key. The
grades certified as
halogen-free by UL
include Halguard 58100,
58205, 58210, 58215 and
58350. The last two exhibit
low post-extrusion shrink-
age for fibre optic
applications.
● Two low-cost 58600 Series compounds. Designed for general-purpose
jacketing applications, Halguard LS-HFFR compounds in this series are more
economical than premium compounds while incurring little compromise in
performance properties. The series includes grades with enhanced flame
retardance as well as lower post-extrusion shrinkage. Halguard 58600 Series
compounds are suitable for cables used in subway, mass transit, cell tower,
data centre and infrastructure applications, as well as internal wiring in
electrical and electronic equipment. The grades certified as halogen-free by
UL include Halguard 58600 and 58610.
The UL certification for Teknor Color applies to 14 concentrates supplied in pellet
form, using ethylene-vinyl acetate (EVA) and polyethylene (PE) polymers as
carrier resins. These new concentrates can be used with the EVA or
polyolefin-based halogen-free flame retardant (HFFR) compounds currently
available.
“The Halguard LS-HFFR product line addresses a wide range of application
requirements, including physical properties, flexibility, processability, flame
retardance, post-extrusion shrinkage and cost,” said Mike Patel, director of
marketing and business development for the vinyl division.
“The addition of halogen-free assessments by UL further expands options for
customers and is particularly advantageous for those seeking to supply
installations in confined spaces or public infrastructure such as mass transit.”
