Heat Shrink Dual Wall Tubes |CoatingTubings | sleevesThe Heat Shrink Dual Wall Tubes are processed by the composition of polyolefin and hot-melt adhesive. It can provide not only insulative protection of general heat shrinkable sleeves, but also waterproof and sealing protection. It is widely used for connecting and waterproofing of the electrical equipment, sealing and fixing of the wire branch and protecting the metal from corroding.
