PE material Heat Shrinkable Tube

Most of the heat shrinkable tubes made of PE, EVA, isoprene and other materials. PE heat shrinkable tube due to its raw materials through a series of production processes to make the product has the characteristics of heating after heat and close wrapped on the quilt object. Generally speaking, PE heat shrinkable tube has the characteristics of insulating layer safety protection, corrosion prevention, leakage and so on. Low voltage PE heat shrinkable tube also has the effect of beautiful decorative design, and it is used in daily life on doorknobs and clothes zippers.

PE heat shrinkable tube according to the voltage level can be divided into 1kV, 10kV, 35kV heat shrinkable tube, 1kV PE heat shrinkable tube color is more, there are red, green, yellow, blue, black, white, yellow green, transparent color. The color of 10kV, 35kV PE heat shrinkable tube is relatively less, only red, green and yellow. There are also some differences in specifications and models. If you want to know more about various models, you can contact our sales staff for consultation and procurement.

There are many raw materials that can be used for the production and processing of heat shrinkable tubes, mainly:

PVC: PVC heat shrinkable tube is a common heat shrinkable tube, its wall thickness is thinner, the price is cheaper, has excellent acid resistance and corrosion, combustion, often used for rechargeable battery coating insulation layer safety protection.

PTFE: PTFE heat shrinkable tube, can withstand high temperature to 260℃, can withstand most of the chemical organic solvents, abrasion resistance fracture, high toughness.

EPDM: EPDM: EPDM heat shrinkable tube, with high physical process performance and wear resistance, is mainly used for cable harness and cable sheath maintenance of electronic components. It is mainly black.

FEP: FEP heat shrinkable tube has excellent wear resistance, does not ignite, not only has similar characteristics with PTFE, but also has thermoplastic, has good processing performance.

Silica gel: silicone heat shrinkable tube is made of silicone rubber, mainly used in medical machinery, electrical products, aerospace, military, electronic components and other applications of wire and cable with certain plasticity and temperature resistance requirements.

There are many materials of heat shrink tube, but these materials are not good or bad, mainly according to the use of the field of heat shrink tube to choose the right material, such as:

1. In terms of battery capacitance, heat shrink tubes made of PVC and PET materials with thin wall thickness, fast shrinkage and many colors can be selected.

2. General electronic products, soft, suitable for low pressure 600V, commonly used EVA heat shrinkable tube; If high pressure resistance is required, rubber is added to EVA material.

3. Requires good wear resistance, you can choose PE or HDPE heat shrinkable tube.

4. Requirements of high temperature resistance, can use fluorine rubber, polyvinylidene fluoride, Teflon materials, etc.

To sum up, heat shrinkable tubes of different materials have their own application fields. In the selection, the suitable materials are mainly selected according to the use and demand.
