Heat-shrinkable Tubing
Applications
High-ratio (HR) heat-
shrinkable tubing, with
expansion ratios as high
as 5.6 to 1, is designed to
accommodate large size
differences between cables
and cable connectors and
backshells, thus simplifying
repair of damaged cable.
High-ratio tubing is
available in semirigid
flame-retardant (SR),
standard (NF), or high-flex
flame-retardant (HF)
material and with or without
factory-applied sealants
and adhesives. The water-
proofing sealant provides
environmental sealing and
is watertight in wet and
corrosive locations. The
thermoplastic adhesive
coating offers excellent
strain relief and environ-
mental sealing.
