Double wall heat shrinkable tubes
Product Description
Description:
Double wall heat shrinkable tube’s inner side is adhered with semi-flexible shrinkable tube of hot melt adhesive.
It has colloidality inwall which is designed specially. The outside is consisted of radiation crosslinked polyolefin.
When it is heated, the inwall will melt . And it will fill holes or gaps when ektexine shrinks. After cooling, the wall
thickness of double wall will be average and well-knit.
