Request a Quote
3:1 Dual wall heat shrink tubing is made of soft and flame retardant polyolefin and hot-melt adhesive double layers without producing any harmful substances. The outer layer is polyolefin insulation flame retardant material which can resist ultraviolet and the inner one is hot-melt adhesive with excellent sealing property.
This product can avoid water, resist corrosion and prevent air leakage mainly applied to the binding and fixing of multiple strands of metal tubing.
