Flame-retardant thermal shrinkable bushing boasts good flame retardation, insulation, softness, low temperature and fast shrinking. It is widely used in wire connection,welding protection, wire marking, the insulation protection of resistance and capacitor, the corrosion protection of metal bar or tubes, and the antenna protection.
Principle of thermal shrinkage: under the high energy radiation, the li near polymer can form network cross-linked structure. The mechanical strength, temperature, chemical solution and aging resistance of cross-linked polymer are greatly improved, especially the acid and alkali resistance.
Color: Black, red, blue, white, yellow, green and transparent. And other colors can be customized.
Shrinking ratio: 2:1. Rated voltage: 600V.
