Product Description

Product Description

W-DW dual-wall adhesive-lined heat shrinkable tubing

Material
Outer layer: Cross-linked modified polyolefin
Inner layer:flame retarded modified hot melt adhesive
Shrink ratio: 3:1 4:1
Continuous use temperature:-40ºC~125ºC;
Shrinkage temperature :100ºC~150ºC
Characteristics
·Semi-hard,Glue flame retarded
·Excellent mechanical, electric and chemical performance;
·Excellent sealing property;
Application:
dual-wall adhesive-lined heat shrinkable tubing is made by co-extrusion of excellent semi-rigid polyolefin compound and special
hot-melt adhesive. It is specially designed for environmental sealing and electrical insulation of wire splices, terminations, and
components for automotive industry and commercial industry. Outer polyolefin provides strain relief and abration protection of
wire connectors and components. Inner adhesive with a wide of operating temperature bonds to different kinds of automotive wire
and cabes to provide sealing insulation protection.
