Heat Shrink Tubing

Heat shrink tubing is a simple and safe solution for insulation and protection of wires, cables, connections, terminals and components. It is a flexible tube that shrinks in diameter and increases in thickness when heated. In this way, it shrinks tightly around the cable or connector and provides excellent insulating properties. A variety of materials are available to meet specific technical requirements: polyolefin (POX), elastomer (PES), fluoropolymer (FPM), polyvinylidene fluoride (PVDF) and polytetrafluoroethylene (PTFE), etc. Heat shrink tubing is available in many colours including "clear". Variants are thin wall, medium wall and thick wall tubings. Dual-Wall variants are also available; this term is used for heatshrinks that already include adhesive. Our shrink ratios range from 2:1 to 6:1.

Heat Shrink Tubing

Heat shrink tubing is a simple and safe solution for insulation and protection of wires, cables, connections, terminals and components. It is a flexible tube that shrinks in diameter and increases in thickness when heated. In this way, it shrinks tightly around the cable or connector and provides excellent insulating properties. A variety of materials are available to meet specific technical requirements: polyolefin (POX), elastomer (PES), fluoropolymer (FPM), polyvinylidene fluoride (PVDF) and polytetrafluoroethylene (PTFE), etc. Heat shrink tubing is available in many colours including "clear". Variants are thin wall, medium wall and thick wall tubings. Dual-Wall variants are also available; this term is used for heatshrinks that already include adhesive. Our shrink ratios range from 2:1 to 6:1.
