Classification And Introduction Of Heat Shrink Tubing

I. Definition
As the name suggests, it is a tube that shrinks when heated. After being heated and shrunk, it is wrapped around the surface of the object, which can play the role of insulation, moisture-proof, sealing, protection, connection, etc., effectively protecting the product from rust, moisture, etc.
Its production is to extrusion-mold the polymer (polymer material) or polymer alloy (multiple polymers) to obtain a tubular intermediate product, and then cross-link it by radiation, expand it by heating, and cool it to get a tubular product with a certain size.

II. Classification
 1. PVC heat shrink tubing
Made of polyvinyl chloride (containing carcinogens), it can shrink when heated above 70℃ and is easy to use. According to the temperature resistance, it can be divided into two series of 85℃ and 105℃, and the products comply with the EU RoHS environmental protection directive. Our company can provide you with high-quality PVC Insulation Busbar products.
Application range

• Used for the outer coating of electrolytic capacitors (heat insulation, explosion prevention) and inductors (insulation).
• Used for monomer or combination packaging of various rechargeable batteries.
• Used for the outer covering of low-voltage indoor busbar copper bars, connectors, and wiring harnesses.
• Used for the covering of lighting and LED pins, guitars, and packaging bottle mouths.
• Used for the outer covering of various tubular items such as tool rods, telescopic rods, and struts.

Advantages
Good high temperature performance, no secondary shrinkage, printable, high efficiency, low equipment investment, and low comprehensive cost, it is a new generation of packaging materials.

 2. PET heat shrink tubing
The heat shrink tubing made of polyester material greatly exceeds the PVC heat shrink tubing in terms of heat resistance, insulation, and mechanical properties. More importantly, the PET heat shrink tubing is non-toxic and easy to recycle. The environmental performance of PET heat shrink tubing is higher than the EU RoHS environmental directive standard and can meet the Sony SS-00259 environmental standard. It will not have a toxic effect on the human body and the environment, and it is more in line with environmental protection requirements. The Heat Shrink Tubing BusBar products produced by our company are also products that meet the RoSH environmental directive.
Application range
Used for the outer covering of electronic components such as electrolytic capacitors (insulation, explosion prevention), inductors (insulation), high-end rechargeable batteries, toys and medical devices (PET heat shrink tubing can be used within the scope of use of PVC heat shrink tubing).
Advantages
Non-toxic, easy to recycle, strong heat resistance, high insulation and strong mechanical properties.

 3. EVA heat shrink tubing
It is a heat shrink tubing made of a special polyolefin material (also called EVA material).
The insulation level of the heat shrink tubing made of EVA and rubber can exceed 600V. If the customer has material requirements for Heat Shrink Tubing BusBar, we will negotiate and try our best to meet them.
Application range
Used for insulation protection of various wiring harnesses, solder joints, inductors, rust and corrosion protection of metals, etc.
Advantages
Low-temperature shrinkage, soft flame retardant, insulation and corrosion resistance, and can be used in high-voltage working environments.

 4. Glue-containing heat shrink tubing
The outer layer of the glue-containing heat shrink tubing is mainly made of high-quality polyolefins, and the inner layer is made of hot melt adhesive composite processing.
Application range

• Widely used in waterproof and air leakage prevention of electronic equipment wiring;
• Sealing and waterproofing of multi-strand wire harnesses;
• Sealing and waterproofing of wire and cable branches, anti-corrosion protection of metal pipelines, and repair of wires and cables;
• Waterproofing of water pumps and submersible pumps.

Advantages

• The outer layer has the advantages of halogen-free flame retardancy, low-temperature shrinkage, softness, insulation, corrosion resistance, and wear resistance.
• The inner layer has the advantages of low melting point, good adhesion, waterproof sealing and mechanical strain buffering performance.
