The difference between PVC heat shrink sleeves and tubes and PET heat shrink sleeves

PVC heat shrinkable sleeving has the special function of shrinking when it meets heat, and it can shrink when heated above 98℃, which is convenient to use. The products are divided into two series of 85℃ and 105℃ according to the temperature resistance, specifications Φ2-Φ200, the products comply with EU RoHS environmental protection directive. Used for electrolytic capacitors and inductors, the products have good high temperature resistance and no secondary shrinkage, and can be printed on behalf of them. For various rechargeable battery single and combination packaging, and design and printing patterns on behalf of customers, and can be cut on behalf of customers. It is used for the outer wrapping of various curtain rods, shower curtain rods, hanging rods, mop rods, broom handles, tool rods, telescopic rods, garden tools, spreader rods and other tubular items. It can also be used for marking and insulating outer wrapping of low-voltage indoor busbar copper rows, connectors and wire harnesses. High efficiency, low investment in equipment and small comprehensive cost. It is used for the wrapping of lightings and LED pins, and the wrapping of guitars and packaging bottle mouths, and is a new generation of packaging material. Whether for civilian, automotive or military use, it is the top choice.

   PET heat shrinkable tube


   PET heat shrinkable tube (polyester heat shrinkable tube) from heat resistance, electrical insulation properties, mechanical properties are greatly exceeded pvc heat shrinkable sleeve, more importantly, PET heat shrinkable sleeve has no toxicity, easy to recycle, the human body and the environment will not produce toxic effects, more in line with environmental protection requirements.


   PET heat shrink tubing environmental performance is higher than the EU RoHs directive standards, 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 (PCNs), etc., which are banned substances for the environmental management of electrolytic capacitors, inductors and other electronic components, high-grade rechargeable batteries, toys and It is the outer covering of electrolytic capacitors, inductors and other electronic components, high-grade rechargeable batteries, toys and medical devices, and can fully meet the export requirements.


   Heat shrinkable tubing with adhesive


   The outer layer of double wall heat shrinkable tubing with adhesive is made of high quality polyolefin alloy, and the inner layer is made of hot melt adhesive compound. After forming, the product is cross-linked and continuously expanded by electron gas pedal irradiation. The outer layer has the advantages of softness, low temperature shrinkage, insulation, anti-corrosion, wear resistance, etc., while the inner layer has the advantages of low melting point, good adhesion, waterproof sealing and mechanical strain buffer performance. It is widely used in wiring waterproof and air leakage prevention of electronic equipment, sealing waterproof of multi-stranded wire harnesses (such as home appliance harnesses, automobile harnesses, etc.), sealing waterproof of wire and cable branches, anti-corrosion protection of metal pipelines, repair of wire and cable, waterproof of wiring of pumps and submersible pumps, etc.


   Double-wall heat-shrinkable sleeving is produced by double-layer co-extrusion process of polyolefin halogen-free flame retardant material and hot melt adhesive. The outer layer is polyolefin with the characteristics of insulation, halogen-free flame retardant, low temperature shrinkage, etc.; the inner layer is hot melt adhesive with the advantages of low melting point, good adhesion, waterproof sealing and mechanical strain buffer, etc.
