tubing, heat shrinkable tubing is a special polyolefin material heat-shrinkable tubing, can also be called EVA material.
Performance:
High temperature shrinkage, soft flame retardant, insulation and corrosion protection. Widely used in a variety of wire harness, solder joints, inductor insulation protection, metal pipe, bar rust, corrosion, etc.. Voltage level 600V.
Polymer materials with the temperature from low to high to go through the glass state - high elasticity state, glass state performance close to plastic, high elasticity state performance close to rubber.
The materials used in heat shrink tubing are glassy at room temperature and become highly elastic when heated.
Use:
The heat shrink tubing is heated to a high elasticity state during production, a load is applied to make it expand, and then it is cooled quickly to a glassy state while maintaining the expansion, and this state is fixed. As soon as it is heated in use, it changes back to a highly elastic state, but then the load is gone and it has to retract.
Containing rubber double-wall heat shrinkable tubing outer layer of high-quality polyolefin alloy, the inner layer of hot melt adhesive composite processing and become. Product molding by the electron gas pedal irradiation crosslinking, continuous expansion and become. The outer layer has the advantages of softness, low-temperature shrinkage, insulation, anticorrosion, wear-resistant, etc., and the inner layer has the advantages of low melting point, good adhesion, waterproof sealing and mechanical strain buffer performance. Widely used in electronic equipment wiring waterproof, anti-air leakage, multi-stranded harness sealing waterproof (such as home appliance harnesses, automotive wiring harnesses, etc.), wire and cable branching at the sealing waterproof, metal piping anticorrosive protection, wire and cable repair, water pumps and submersible pumps wiring waterproof and other occasions.
