Top quality heat shrink tubing with 3:1 ratio, dual wall adhesive lined, ROHS compliant cable sleeve Our waterproof heat shrink tubing forms water-tight seal when cooled. Best marine heat shrink tubing Flame retardant jacket. Shrink tube temperature starts at 158°f (70c) totally shrunk at 248°f (120c) Our cable wrap has electrical insulation, corrosion & high temperature resistance, & great tightness High Resistance to Chemicals & Oils. Ideal for usage in the automotive industry and electrical needs Kable Kontrol Dual wall adhesive lined 3:1 heat shrink tubing is made from a specially formulated, cross-linked polyolefin that is co-extruded with a meltable adhesive sealant. Our industrial heat-shrink tubing shrinks to 1/3 of its original size. It offers excellent electrical, chemical and physical properties. This tough, flexible, flame retardant tubing can be used for electrical insulation, wire bundling, lightweight harnessing, and wire strain relief in a variety of home, commercial, industrial, and military applications. When heated with a heat gun, the tubing begins to shrink, the inner adhesive layer begins to melt and flow (similar to hot melt glue). When the heatshrink tubing has shrank and cooled, the inner layer forms an adhesion layer between the heat shrink tube and the wire or component, providing a protective water-tight seal. It is an excellent way to terminate the ends of your shrink tubing, creating a tight, professional finish. Additionally, it is in compliance with RoHS. Our top quality heat shrinking tubing has several benefits compared to many wire wraps around. It is not only waterproof but also corrosion resistant, has good tightness and electrical insulation with high temperature resistance, making it an ideal choice of cable sleeve wire wrap for electrical wires applications, marine and automotive industry, and for general cable management purposes.
