Since the heat shrink tubing base material is polyethylene poly***blended system, its melting temperature is about 115 to 135 ℃ between.
Heat shrinkable tubing is a special heat shrinkable tubing made of polyolefin, which can also be called EVA. The outer layer of high-quality soft cross-linked polyolefin material and the inner layer of hot melt adhesive composite processing and become, the outer layer of material insulation corrosion, wear-resistant and other characteristics, the inner layer has a low melting point, waterproof sealing box high adhesion and other advantages.
PVC heat shrinkable tubing
PVC heat shrinkable tubing has a special function of heat shrinkage, heating above 98 ℃ can be contracted, easy to use. The products are divided into two series according to the temperature resistance of 85℃ and 105℃, specifications Φ2-Φ200, the products comply with the EU RoHS environmental protection directive. Used for electrolytic capacitors and inductors, the products have good performance of high temperature resistance, no secondary shrinkage, and can be printed instead. Used for various rechargeable batteries, single, combination packaging, and design, printing patterns, and can be cut on behalf of customers. Used for all kinds of curtain rods, shower curtain rods, hanging rods, mop rods, broom handles, tool rods, telescopic rods, garden tools, spreader rods and other tubular items of outer wrapping. It can also be used for marking and insulating outer wrapping of copper rows, connectors and wire harnesses of low-voltage indoor bus bars. High efficiency, low equipment investment, small comprehensive cost. It is used for the wrapping of lamps and LED pins, and the wrapping of guitars and package bottle mouths, which is a new generation of packaging materials. Whether it is for civil, automotive or military use, it is the top choice.
PET heat shrinkable tubing
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 is non-toxic, easy to recycle, the human body and the environment will not have a poisonous effect, and 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 medical devices, and can fully meet the export requirements.
