Closure patch for wraparound HSS manufacturers tell you that heat shrink tubing is a special polyolefin material heat shrink tubing. The outer layer is made of high-quality and soft cross-linked polyolefin material and the inner layer of hot melt adhesive. The outer layer material has the characteristics of insulation, corrosion resistance, wear resistance, etc. advantage.

The performance of heat shrinkable tube: Closure patch for wraparound HSS manufacturers tell you that it has the functions of high temperature shrinkage, soft flame retardant, insulation and anti-corrosion. It is widely used in insulation protection of various wiring harnesses, solder joints and inductors, and anti-rust and anti-corrosion of metal pipes and rods. Voltage class 600V.
As the temperature changes from low to high, the polymer material goes through a glass state - a high elastic state. The performance of the glass state is close to that of plastic, and the performance of the high elastic state is close to that of rubber.
The material used in the heat shrinkable tube is glassy at room temperature and becomes highly elastic when heated.
Use: Closure patch for wraparound HSS The manufacturer tells you to heat the heat shrinkable tube to a high elastic state during production, apply a load to expand it, and quickly cool it while maintaining the expansion to make it into a glass state, and this state is fixed . Closure patch for wraparound HSS manufacturers tell you that as soon as it is heated, it will return to a high elastic state, but when the load is gone, it will retract.
