Glue-lined heat shrink made from co-extrusion of polyolefin and hot-melt adhesive was certificated by UL and CSA, RoHS compliant, and formaldehyde-free. 4:1 automobile special grade heat shrink tube, special white hot melt adhesive, better sealing, and keep your equipment safe for a long time.

Dual wall heat shrink tubing is good electrical insulation, good sealing, corrosion resistance, and high-temperature resistance. Anti-aging, tough, not easy to break. It is widely used for industrial, ship, wire links, anti-rust, and anti-corrosion protection.
