What are the characteristics of the three types of heat shrink tubing?

Heat shrink tubing comes in various types, each with its own set of characteristics tailored to specific applications.

1. PVC heat shrink tubing

PVC heat shrink tubing has a special function of shrinking when exposed to heat. It can be reduced by heating to 98°C and is easy to use. Products are divided into two categories according to temperature resistance: 85°C and 105°C, with standards Φ2-Φ200. The products correspond to the EU RoHS environmental directive. It must be used in electrolytic capacitors and inductors. The equipment has good high temperature resistance and no secondary shrinkage. It must be printed on your behalf. It needs to be used in the single and combined packaging of many rechargeable batteries. At the same time, we can design and print the patterns on our behalf, and at the same time, we can cut them for customers. It must be used for the outer covering of many tubular products such as curtain rods, shower curtain rods, hanging rods, mop rods, broom handles, tool rods, telescopic rods, garden tools, support rods, etc. At the same time, it can be used for marking and insulating outer coating of low-voltage indoor busbar copper bars, connectors, and wire harnesses. The efficiency is good, the equipment investment is minimal, and the collective cost is small. It must be used for wrapping lighting, LED pins, guitars, and bottle packaging. It is definitely a new generation of packaging material. Whether it is for civilian, automotive or military use, the choice is yours.

2. PET Heat Shrinkable Tube

PET heat shrinkable tubing (polyester heat shrinkable tubing) shows that its heat resistance, electrical insulation, and mechanical properties are much greater than those of PVC Heat Shrinkable Sleeves. What needs to be more cautious is that PET Heat Shrinkable Sleeves are non-toxic and easy to recycle. Compared with the human body and the surrounding environment, it is difficult to cause poisonous disturbance, and it is more environmentally friendly.

The environmental performance of PET heat shrink tubing is far greater than the EU RoHs directive standard and must meet Sony SS-00259 environmental protection standards. Does not contain cadmium (Cd), lead (Pb), mercury (Hg), hexavalent chromium (CrVI), polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBBEs/PBDEs), polychlorinated biphenyls (PCB), polychlorinated terphenyls ( PCT), polychlorinated naphthalenes (PCN) and other level 1 environmental management banned substances must be the outer coverings of electrolytic capacitors, inductors and other electronic components, high-end rechargeable batteries, toys and medical devices, and they are fully beginning to meet export permissions.

3. Glue-containing Heat Shrinkable Tube

The outer layer of the adhesive-containing double-wall heat shrinkable sleeve is made of high-quality polyolefin alloy, and the inner layer is also made of hot melt adhesive composite. After the equipment is formed, it is then irradiated by an electron accelerator, cross-linked, connected and continuously transformed. The outer layer has features such as softness, low-temperature shrinkage, insulation, anti-corrosion, and wear resistance, while the inner layer has features such as low melting point, good adhesion, waterproof sealing, and mechanical strain buffering. It is widely used in wiring waterproofing and air leakage prevention of electronic equipment, sealing and waterproofing of multi-strand wiring harnesses (such as home wiring harnesses, automobile wiring harnesses, etc.), sealing and waterproofing of wire and cable environments, anti-corrosion maintenance of metal pipelines, and embroidery/embroidery of wires and cables. , the wiring of water pumps and submersible pumps is waterproof and other occasions.

These characteristics make each type of heat shrink tubing suitable for specific applications, ranging from electrical insulation and wire harnessing to cable identification and environmental protection. Understanding the properties of each type helps in selecting the most appropriate heat shrink tubing for a particular application.
