Versafit V4
Very-thin-wall, highly flame-retardant,
metric-sized heat-shrinkable tubing
Versafit V4 heat-shrinkable tubing is
a cost-effective, environmentally
friendly choice for many commercial
applications. Versafit V4 tubing is a
very thin-wall version of Versafit,
a specially formulated polyolefin
with low recovery temperature,
excellent flexibility, and high flame-
retardance (VW-1).
Versafit V4 tubing is typically applied
where space savings is important,
offering the ability to pack components
more closely than is possible with
standard tubings. Versafit V4 tubing
can shrink more than twice as fast
as standard products. This rapid
shrinking may be important in the
prevention of overheating of
temperature-sensitive components.
Unlike other typical flame-retardant
tubings, Versafit V4 tubing is free of
polybrominated biphenyls (PBBs)
and polybrominated biphenyl oxides
(PBBOs). In Europe, these chemicals
are classified as environmentally
hazardous substances.
Versafit V4 products are UL-recognized
at 125°C, 300 V, and CSA-certified at
125°C, 150 V, with UL VW-1 and
CSA OFT flame-retardancy ratings.
