The environmental performance of PET heat shrinkable tube is higher than the EU RoHs directive standard, and can reach Sony SS-00259 environmental protection standard. It does not contain 65,438+such as cadmium (Cd), lead (Pb), mercury (Hg), hexavalent chromium (CrVI), polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBBEs/PBDEs), polychlorinated biphenyls (PCB), polychlorinated terphenyl (PCT) and polychlorinated naphthalene (PCN). The outer layer of double-wall heat shrinkable sleeve with glue is made of high-quality polyolefin alloy and the inner layer is hot melt adhesive. This product is formed by irradiation and crosslinking of electron accelerator and continuous expansion after molding. The outer layer has the advantages of softness, low temperature shrinkage, insulation, corrosion resistance and wear resistance, while the inner layer has the advantages of low melting point, good adhesion, waterproof sealing and mechanical strain buffering performance. Widely used in electronic equipment wiring waterproof, leak-proof, multi-strand wire harness sealing waterproof (such as home appliance wire harness, automotive wiring harness, etc.). ), wire and cable branch sealing waterproof, metal pipeline anticorrosion, wire and cable repair, water pump and submersible pump wiring waterproof and other occasions.
Double-wall heat shrinkable sleeve is produced by double-layer extrusion process of polyolefin halogen-free flame retardant material and hot melt adhesive. The outer layer is made of polyolefin, which has the characteristics of insulation, halogen-free flame retardant and low temperature shrinkage. The inner layer is hot melt adhesive, which has the advantages of low melting point, good adhesion, waterproof sealing and mechanical strain buffering.
