The characteristic of PET heat shrinkable tube is that it can be degraded and used in products with environmental
protection grade requirements. PET heat-shrinkable tubing (polyester heat-shrinkable tubing) greatly exceeds PVC
heat-shrinkable tubing in terms of heat resistance, electrical insulation performance, and mechanical properties.
More importantly, PET heat-shrinkable tubing is non-toxic and easy to recycle. The human body and the environment
will not produce toxic effects,and it is more in line with environmental protection requirements. The environmental
performance of PET heat shrinkable tube is higher than the EU RoHs directive standard, and can reach the Sony
SS-00259 environmental protection standard.It does not contain cadmium, lead, mercury, hexavalent chromium,
polybrominated biphenyls, polybrominated diphenyl ethers, polychlorinated biphenyls, polychlorinated terphenyls,
polychlorinated naphthalenes and other prohibited substances for environmental management. It is an electrolytic
capacitor, inductor and other electronic components, high-end The outer covering of rechargeable batteries, toys
and medical equipment can fully meet the export requirements.
Glue-containing heat shrinkable tube
The outer layer of rubber-containing double-wall heat-shrinkable tubing is made of high-quality polyolefin alloy,
and the inner layer is composited with hot melt adhesive. After the product is formed, it is irradiated by an electron
accelerator,cross-linked, and continuously expanded. The outer layer has the advantages of softness, low temperature
shrinkage,insulation, anti-corrosion, and wear resistance. The inner layer has the advantages of low melting point,
good adhesion,waterproof sealing and mechanical strain buffering properties. It is widely used in the wiring
waterproof and air leakage of electronic equipment, the sealing and waterproofing of multi-strand wiring harness
(such as home wiring harness,automobile wiring harness, etc.), the sealing and waterproofing of wire and cable
branches, the corrosion protection of metal pipelines, the repair of wires and cables, water pumps and The wiring
of the submersible pump is waterproof and other occasions. There are several types of PE heat-shrinkable tubes
according to voltage levels, which are used for motor lead wires and inductors, and high-voltage ones are used for
wire insulation, busbar wrapping, and so on.
The above three are the three most common heat shrinkable tubes in circuit design, and are also the three mainstream
heat shrinkable tubes on the market. Through the introduction of this article, I believe everyone has a more detailed
understanding of the functions of these three heat shrinkable tubes. It can be understood that the heat shrinkable tube
can not only be used for power supply design, but also can play a huge role in other fields.
