Heat shrinkable band used hollow-wall pipe, metal spiral pipe, pipe insulation. Heat shrinkable band is polylene radiation crosslinking after Sol quality heat from the heat with a connecting tube. Because of the gas fire Yan baking process, the memory crunch, heat shrinkable band and PE pipe can be formed between a molten-hot melt adhesive layers, Sol and with the heat between the PE materials other substances due to the affinity After cooling the connector sealing effect was quite good. Therefore, heat shrinkable band is hollow pipe wall. Spiral Pipe ideals such as plastic pipe connecting a tube.

Its performance characteristics : contraction speed and good s
