Heat shrinkable tube is a kind of heat shrinkable tubing, also known as heat shrinkable tubing, commonly used to protect a variety of wires and cables, a lot of friends do not know it very well, don't know what the heat shrinkable tube material, in fact, can be used for the production of raw materials to make the production of heat shrinkable tubing, there are several kinds of the following:
1, PVC
pvc Heat shrink tubing is more common heat shrink tubing, its wall thickness is thinner, cheaper, with excellent resistance to acid and corrosion, combustibility, commonly used in rechargeable batteries wrapped insulation layer safety protection.
2, PE
that is, high-pressure polyethylene materials, widely used in household appliances or electronic components maintenance and other industries, but also PE as a substrate, and other polymers **** mixed, such as PE and EDPM **** mixed into a high compression strength, aging-resistant heat-shrinkable tubing made of outdoor cables.
3, PTFE
Polytetrafluoroethylene, commonly known as Teflon heat shrinkable tubing, can withstand high temperatures of 260 ℃, resistant to most of the analysis of chemical organic solutions, anti-wear fracture toughness.
4, EPDM
Also known as EPDM heat shrinkable tubing, with high-quality physical process performance and abrasion resistance, mainly used for cable vehicle harness electronic components of the cable sheath maintenance, the main color is black.
5, FEP
that is, polyperfluorobutadiene, with excellent abrasion resistance, does not ignite, both with similar characteristics to PTFE, but also has a good processing performance of thermoplastics.
6, silicone
Silicone heat shrinkable tubing is made of silicone rubber, mainly used in medical machinery, electrical products, aerospace, military, cars, electronic components parts, transformers, engines and other wires and cables have a certain degree of plasticity and temperature resistance requirements of the field.
Second, the material of the heat shrinkable tube which is better
The heat shrinkable tube material is numerous, but these materials are not good or bad, mainly based on the use of the heat shrinkable tube field to choose the right material, such as:
1, battery capacitors with the requirements of ultra-thin, fast shrinkage, color, then more PVC and PET heat shrinkable tube.
2, general electronics, require soft, low voltage 600V, then commonly used eva heat shrink tubing; high voltage is used eva add rubber.
3, the requirements of better abrasion resistance, the choice of PE or HDPE heat shrinkable tube.
4, the requirements of high temperature resistance, you can use fluoroelastomer, polyvinylidene fluoride, Teflon materials.
In summary, the different materials of heat shrinkable tubing have their own areas of application, when choosing the main use and demand to choose the right material.
