Adhesive Heat Shrink Sleeving is lined with a layer of hot melt adhesive on the inner wall which is heated and shrunk to provide sealing and insulation protection. Naxilai adhesive heat shrink sleeving meets environmental standards such as Reach & RoHS. Double wall adhesive heat shrink is made of high polymer, scientifically formulated and mechanically blended into a high polymer alloy, the product is formed by irradiation, cross-linking, and continuous expansion by an electron accelerator after molding. The outer layer of dual wall heat shrink tube is made of cross-linked polyolefin material, and the inner layer is hot melt adhesive. The outer layer has the advantages of insulation, corrosion prevention, and other advantages. The inner layer has the advantages of low melting point, waterproof sealing, and mechanical strain cushioning performance. It is applied to the waterproof and air leakage prevention of the wiring of electronic equipment, the sealing and fixation of wire branches, the anti-corrosion protection of metal pipelines, the repair of wires and cables, and the waterproof of the wiring of water pumps and submersible pumps.
