Cut Sheet

CRSM wraparounds are a fast and
permanent cable repair and sealing
system. The repair sleeve is quickly
fitted in place by means of its rail and
c
hannel closure. A moisture-proof,
insulating and tight-fitting repair is then
obtained in one step by heating, which
makes the sleeve diameter shrink and
the sealant coating melt and flow
into interstices. Because of its
heat-shrinkability, each CRSM size will
fit several different cable diameters.
The sealant exhibits excellent bonding
and sealing characteristics to all
materials commonly used in the various
cable and sheath constructions, such
as plastic, rubber, lead and aluminium.
CRSM wraparounds are made of an
abrasion and corrosion resistant
semi-rigid material, and are one result
of our extensive capability in materials
technology.
As the world’s leading maker of
heat-shrinkable materials, we offer a
wide range of tubing and moulded
parts for any application where a tight,
insulating or fluid resistant cover is
required over uniform or irregularly
shaped objects. These products are
available in a wide range of
formulations to meet the demands of
the growing world of energy.
