PE and PVC heat shrink sleeving
Heat shrinkable sleeving according to the material points have PVC heat shrinkable sleeving, PE heat shrinkable sleeving, PTFE heat shrinkable sleeving, PVDF heat shrinkable sleeving, EPDM heat shrinkable sleeving, etc., of which PE heat shrinkable sleeving and PVC heat shrinkable sleeving are close to the indicators, today we analyze PE heat shrinkable sleeving and PVC heat shrinkable sleeving which is good.
How to choose between PE and PVC heat shrink sleeving? First of all, from the material itself for comparison:
Name, PVC is polyvinyl chloride, PE is polyethylene; price, PVC is cheap, PE expensive; performance, are not heat-resistant (some people have made changes to the PE molecular structure, namely PEX and PERT, can be resistant to high temperatures); application, PVC is more widely used, and PVC is cheap, PE is far less widely used; health performance, PVC because there is chlorine, when heated will release chlorine, and the reflection of water in the air, resulting in hydrogen chloride gas, toxic to humans, while PE contains only two elements of carbon and hydrogen, health non-toxic
How to choose between PE and PVC heat shrink sleeving? A comparison of the finished product:
PE heat-shrinkable sleeving is made of a special polyolefin material, which can also be called EVA. PE heat-shrinkable sleeving performance: with low-temperature shrinkage, soft and flame retardant, insulation and corrosion protection. It is widely used in the insulation protection and sealing of various wire harnesses, solder joints and inductors, as well as in the rust and corrosion prevention of metal pipes and rods. PE heat-shrinkable sleeving is a glassy material at room temperature and becomes a highly elastic material after heating.
PE and PVC heat shrink sleeving has the special function of shrinking when heated to 98°C or more, which makes it easy to use. The products are divided into two series according to the temperature resistance of 85℃ and 105℃, and the products comply with the EU RoHS directive. Used for electrolytic capacitors and inductors, the products have good high temperature resistance and no secondary shrinkage, and can be printed on behalf of them. Used for various rechargeable batteries in single and combination packaging, and design and print patterns on behalf of customers, and can be cut on behalf of customers. For the outer wrapping of various curtain rods, shower curtain rods, hanging rods, mop rods, broom handles, tool rods, telescopic rods, garden tools, spreader rods and other tubular items. It can also be used for marking and insulating the outer covering of copper rows, connectors and wire harnesses of low-voltage indoor busbars. High efficiency, low investment in equipment and small overall cost. It is a new generation of packaging material for the wrapping of light fittings, LED pins, and the wrapping of guitars and packaging bottle mouths. Whether for civil, automotive or military use.
So in general terms PE and PVC heat shrink sleeving is better in terms of temperature resistance, environmental protection, etc. PVC thermoplastic tubing is more widely used, the price is lower than PE heat-shrinkable tubing, and the main uses and application areas are gradually different. Relatively PE heat-shrinkable tubing to be better, but specific analysis of specific issues, PE and PVC heat shrink sleeving, heat-shrinkable tubing regardless of which material used in different areas depend on the actual occasion, its good or bad can not be the same argument
