CRN-1/4-X-SP

CRN
Semirigid, flame-retardant, polyolefin
heat-shrinkable tubing
Heat-shrinkable CRN tubing is ideally
suited for wire strain-relief applications.
It provides excellent strain-relief and
insulation of weak points such as wire
splices and terminations. CRN tubing
helps ensure a reliable connection
because it transfers the flex stress
away from typically sensitive points
such as solder and crimp joints.
CRN tubing has a broad range of uses
including component protective covering
and packaging. The flame-retardant
material is fabricated from radiation-
crosslinked polyolefin and exhibits
excellent mechanical and chemical
properties. It meets major military
and industrial specifications for an
all-purpose, semirigid tubing.
CRN tubing is abrasion-resistant.
It’s superior chemical properties
permit satisfactory performance
after exposure to common chemicals
and solvents.
Only a few sizes of CRN tubing are
required to cover a wide range of
substrate diameters.
