Request a Quote
The 3:1 Semi-rigid dual wall heat shrink tubing is made of semi-rigid EVA and hot-melt adhesive. The outer EVA material is hard and resistant to abrasion. And when heated, the inner layer hot-melt adhesive will melt and stick to the surface of the wire and realizes waterproof and sealing.
So the heat shrink tubing has three major specialties, insulation, sealing and abrasion resistance. It can be widely used for insulation of wires and cables outdoors and indoors, along with corrosion and abrasion resistance for all kinds of pipes.
