PET heat shrinkable tubing (polyester heat shrinkable tubing) from the heat resistance, electrical insulation properties, mechanical properties are greatly more than pvc heat shrinkable tubing, more importantly, PET heat shrinkable tubing has non-toxic, easy to recycle, the human body and the environment will not have a toxic effect, more in line with the requirements of environmental protection.
The environmental performance of PET heat shrinkable tubing is higher than the EU RoHs Directive standard, and can reach Sony SS-00259 environmental standards. It does not contain cadmium (Cd), lead (Pb), mercury (Hg), hexavalent chromium (CrVI), polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBBEs/PBDEs), polychlorinated biphenyls (PCBs), polychlorinated terphenyls (PCTs), polychlorinated naphthalenes (PCN) and other banned substances of the 1st level of environmental management, and it is the best choice for the outer wrapping of electrolytic capacitors, inductors and other electronic components, high-grade rechargeable batteries, toys and The outer covering of medical devices can fully meet the export requirements.
The double-wall heat shrinkable tubing is made of high quality polyolefin alloy in the outer layer and hot melt adhesive in the inner layer. After the product molding by the electron gas pedal irradiation crosslinking, continuous expansion and become. The outer layer has the advantages of softness, low-temperature shrinkage, insulation, anticorrosion, wear-resistant, etc., and the inner layer has the advantages of low melting point, good adhesion, waterproof sealing and mechanical strain buffer performance. Widely used in electronic equipment wiring waterproof, anti-air leakage, multi-stranded harness sealing waterproof (such as home appliance harness, automotive wiring harness, etc.), wire and cable branching at the sealing waterproof, metal piping anticorrosive protection, wire and cable repair, water pumps and submersible pumps wiring waterproof and other occasions.
Double-wall heat shrinkable casing using polyolefin halogen-free flame retardant materials and hot melt adhesive double **** extrusion process. The outer layer of polyolefin has the characteristics of insulation, halogen-free flame retardant, low-temperature shrinkage, etc.; the inner layer of hot melt adhesive has the advantages of low melting point, good adhesion, waterproof sealing and mechanical strain buffer.

Product features:
The heat shrinkable tubing has excellent flame retardant and insulating properties, very soft and flexible, low shrinkage temperature and fast shrinkage, which can be widely used in the connection of wires, wire end treatment, solder joint protection, wire harness marking, insulation protection of resistor-capacitor, corrosion protection of metal rods or tubes, and protection of antennae. Under the action of high-energy rays, the linear polymer material forms a three-dimensional mesh cross-linking structure. After crosslinking the polymer material in the mechanical strength, temperature resistance, chemical solvent resistance, aging resistance and other aspects of the great improvement, especially acid, alkaline resistance has been greatly improved.
Flame-retardant Heat shrinkable tube has excellent un-flammability, flexibility, and insulation. It is suitable for various electric insulation and bonding of cables and connectors and widely applied for connecting or end- handling, electric wire, insulating and other electrical equipment. It is suitable for various electric insulation and bonding of cables and connectors and widely applied for connecting or end- handling, electric wire, insulating and harness of electric wire, corrosion-proof of metallic rods or tubes, and antenna
