Available in: Americas Europe Asia Pacific
■■■
Very-Thin-Wall, Very
Flexible, Highly Flame-
Retardant, Low Recovery
Temperature, ZEROHAL
Polyolefin Tubing
Product Facts
■2:1 shrink ratio
■Highly flame-retardant;
UL/CSA VW-1 flammability
rating
■Very thin wall provides
space savings and rapid
shrinking
■Low shrink temperature
further reduces installation
time and risk of damage to
temperature-sensitive
components
■Environmentally friendly
tubing essentially free of
halogens
■Emits minimal amounts of
toxic or acid gasses when
burned
■RoHS compliant
Specifications/Approvals
Applications
Electrical insulation and
protection of in-line compo-
nents, disconnect terminals,
and splices in computers,
appliances, and other com-
mercial electronic products.
Typically used where space
saving is important. Offers
the ability to pack compo-
nents more closely than is
possible with standard
tubings. Used for strain
relief on high-density con-
nectors. Suitable for use in
rail and mass transit vehi-
cles, buildings, and other
enclosed areas where
emission of toxic gasses
from burning materials con-
taining halogens is very
undesirable.
Installation
Minimum shrink
temperature: 70°C [158°F]
Minimum full recovery
temperature: 90°C [194°F]
Operating Temperature Range
-30°C to 125°C
[-22°F to 257°F]
