SH135 is flexible yet it provides greater electrical, chemical, and abrasion resistance and greater mechanical strength than that of shrinkable PVC tubing. It not only insulates, it can also encapsulate giving a watertight fit. Won't crack or peel. It's non-corrosive, has excellent resistance to soldering irons, oils, solvents, acids, alkalis, fuels, hydraulic fluids, and fungus. Shrink Ratio--2:1 (50%). Shrinks when exposed to 250°F. Longitudinal shrinkage: 5%. Dielectric Strength: 1300V/MIL. Colored tubing is self-extinguishing; clear tubing is slow burning. OPER. TEMP.: -55°C to +135°C. Uses: Strain relief, jacketing material, component insulation. Meets MIL-I-23053/5A, Class 1,2 MIL-I-7444B, AMS 3636B, AMS 3637A, ASTM D876, ASTM D150, ASTM D257,ASTM D2671, ASTM D792.
