DWFL Fully flame-retardant Dual-wall Heat Shrinkable Polyolefin Tubing
Application
DWFL fully flame-retardant dual-wall adhesive-lined heat shrinkable tubing is made by co-extrusion of excellent flame-retardant polyolefin compound and flame-retardant hot-melt adhesive to provide the optimum solution for applications where full retardancy is preferred, or specified. It is suitable for use in the automotive harness market and other harsh environments. DWFL has high shrink ratio to meet most component sealing requirements, and is compatible with a wide range of application equipment. It is typical used in the insulation and sealing of electrical and electronic components, automotive, communication, aerospace and military industry.
Characteristics
v High shrink ratio: 4:1
v Outer flame-retardant polyolefin and flame-retardant adhesive provide full flame retardancy.
v Excellent hot-melt adhesive provides good environmental sealing protection.
