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 radiationcrosslinked 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.
