Heat shrinkable bushing is a special heat shrinkable sleeve made of polyolefin.
Properties: low temperature shrinkage, soft flame retardant, insulation and anticorrosion function. Widely used in various wiring harness, solder joint, inductance insulation protection, metal pipe, rod anti-rust, anti-corrosion and so on. Voltage level 600V.
Polymer materials undergo glassy-high elastic state from low to high temperature, and their properties in glassy state are close to those of plastics, and in high elastic state they are close to those of rubber.
The material used for the heat shrinkable tube is glass state at room temperature and becomes high elastic state after heating.
Use: Heat shrinkable tube to high elastic state during production, apply load to make it expand, cool rapidly while keeping expansion, make it enter glass state, this state is fixed. When heated, it will return to high elastic state, but when the load is gone, it will shrink back.
