Heat-shrinkable sleeves are divided into PVC heat-shrinkable sleeves, PE heat-shrinkable sleeves, PTFE heat-shrinkable sleeves, PVDF heat-shrinkable sleeves, EPDM heat-shrinkable sleeves, etc., among which PE heat-shrinkable sleeves and PVC heat-shrinkable sleeves The indicators of the casing are close. Today we will analyze which is better, PE heat shrinkable casing or PVC heat shrinkable casing.

How to choose PE heat shrinkable sleeve and PVC heat shrinkable sleeve? First compare from the material itself:

In terms of name, PVC is polyvinyl chloride, and PE is polyethylene; in terms of price, PVC is cheap and PE is expensive; in terms of performance, they are not heat-resistant (some people have changed the molecular structure of PE, namely PEX and PERT, which can withstand high temperatures); In terms of application, PVC is more widely used, which is related to the cheapness of PVC. The application of PE is far less extensive; in terms of hygienic performance, because PVC contains chlorine, it will release chlorine gas when heated, and react with water in the air to produce hydrogen chloride. Gas, which is poisonous to the human body, while PE only contains two elements of carbon and hydrogen, which is hygienic and non-toxic

How to choose PE heat shrinkable sleeve and PVC heat shrinkable sleeve? Comparison from the finished product:

The PE heat shrinkable sleeve is made of a special polyolefin material, which can also be called EVA material. PE heat-shrinkable sleeve performance: it has the functions of low-temperature shrinkage, softness, flame retardancy, insulation and anti-corrosion. Widely used in insulation protection, sealing and anti-corrosion of various wiring harnesses, solder joints and inductors, rust and corrosion protection of metal pipes and rods, etc. Voltage level 600V. It is common for the product to withstand a temperature of 105°C to 135°C. It complies with the RoHS environmental protection standard and is flame retardant. The polymer material will go through a glass state-high elastic state as the temperature changes from low to high. The performance in the glass state is close to that of plastic, and the performance in the high elastic state close to rubber. The material used for PE heat shrinkable tubing is glassy at room temperature and becomes highly elastic after heating. 

The PVC heat-shrinkable sleeve has a special function of shrinking when heated, and it can shrink when heated above 98°C, which is convenient to use. The products are divided into two series of 85℃ and 105℃ according to the temperature resistance, and the products comply with the EU RoHS environmental protection directive. Used in electrolytic capacitors and inductors, the product has good high temperature resistance and no secondary shrinkage, and can be printed instead. It is used for single and combined packaging of various rechargeable batteries, and can design and print patterns on behalf of customers, and can also cut them on behalf of customers. It is used for the outer coating of various curtain rods, shower curtain rods, hanging rods, mop rods, broom handles, tool rods, telescopic rods, garden tools, poles and other tubular items. It can also be used for low-voltage indoor busbar copper bars, connectors, wiring harness identification, and insulation coating. High efficiency, less investment in equipment, and low overall cost. It is a new generation of packaging materials for lighting, LED pin wrapping, and guitar and packaging bottle wrapping. No matter it is for civil, vehicle or military use, it can be used.

Therefore, in general, PE heat-shrinkable sleeves are better in terms of temperature resistance and environmental protection. PVC thermoplastic pipes are more widely used, and the price is lower than that of PE heat-shrinkable sleeves. The main uses and application fields are gradually different. It is better than PE heat-shrinkable sleeve, but specific analysis of specific issues, no matter which material of heat-shrinkable sleeve is used in different fields depends on the actual occasion, its quality cannot be the same.
