How to choose heat shrink tubing?

Heat shrink tubing, although not directly involved in the composition of electronic circuits, has a role to play in protecting vital devices and circuits. But the role of heat shrink tubing goes far beyond the protection of circuits.

There are a number of other uses for heat shrink tubing that go beyond the protection of electrical circuits.

PVC heat shrink tubing: The types of heat shrink tubing can be classified in great detail according to the different materials, specifications, thicknesses and uses, and PVC heat shrink tubing has the special function of shrinking when heated above 98°C, making it 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 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. It can also be used for marking and insulation outer covering of low voltage indoor busbar copper rows, connectors and wire harnesses. How to choose heat shrink tubing, High efficiency, low investment in equipment and small comprehensive cost. It is also used for the wrapping of light fittings, LED pins, and the wrapping of guitars and packaging bottle mouths, and is a new generation of packaging material. Whether for civil, automotive or military use, it is the top choice.

PET heat-shrinkable tubing (polyester heat-shrinkable tubing) is characterised by its biodegradable nature and is used in products with environmentally friendly grades. PET heat-shrinkable tubing (polyester heat-shrinkable tubing) greatly exceeds pvc heat-shrinkable tubing in terms of heat resistance, electrical insulation properties and mechanical properties.  The environmental performance of PET heat shrinkable tubing is higher than the EU RoHs directive standard and can reach the SonySS-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 Class 1 substances banned for environmental management. It is the outer covering for electronic components such as electrolytic capacitors, inductors, high-grade rechargeable batteries, toys and medical devices, and fully meets export requirements.

How to choose heat shrink tubing, 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 of hot melt adhesive is compounded and processed. After forming, the product is cross-linked and continuously expanded by electron accelerator irradiation. The outer layer has the advantages of softness, low temperature shrinkage, insulation, anti-corrosion and wear resistance, 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 the wiring of electronic equipment, air leakage prevention, sealing and waterproofing of multi-stranded wire harnesses (such as home appliance harnesses, car harnesses, etc.), sealing and waterproofing of wire and cable branches, anti-corrosion protection of metal pipelines, repair of wires and cables, waterproofing of water pumps and submersible pump wiring, etc. PE heat-shrinkable tubes are divided into several types according to voltage levels, used in motor lead wires and inductors, high-voltage ones are used in wire insulation, busbar wrapping and so on.
