Mobile WebSiteHeat shrinkable tube is a kind of special polyolefin material heat shrinkable sleeve, which can also be called EVA material. The outer layer is made of high-quality soft cross-linked polyolefin material and the inner layer of hot melt adhesive. The outer layer material has the characteristics of insulation and corrosion resistance, wear resistance, etc., and the inner layer has a low melting point, waterproof seal and high adhesion. advantage.
Heat shrink tubing is used for electrical insulation and mechanical protection. It can be divided into thin-walled pipes, middle-walled pipes and thick-walled pipes. There are single-walled pipes without glue layer or double-walled pipes with glue layer. Heat shrink tubing is made of polyolefin (POX), elastomer (PES), fluoropolymer (FPM), polyvinylidene fluoride (PVDF), and polytetrafluoroethylene (PTFE). According to different applications, products with different shrinkage rates can be supplied, with shrinkage rates ranging from 2: 1 to 6: 1.
From heat-shrinkable tubing with a glue layer to transparent heat-shrinkable tubing, you can provide insulation for your cables while inspecting the internal cables.
Application of heat shrinkable sleeve
1: For how to shrink the sleeve, it is best to start from the middle of the sleeve, then gradually shrink to the other end, and then start to shrink again from the middle and gradually shrink to the other end. This prevents air from trapping inside the casing.
2: The heat-shrinkable sleeve also shrinks longitudinally. This must be taken into account when cutting the casing.
3: The shrinkage starts from both ends and then to the middle end to minimize longitudinal shrinkage. This is also possible.
However, in order to avoid air trapped inside the casing and prevent the middle portion of the casing from shrinking excessively, another way is to start shrinking from one end and the most important thing is to slowly shrink one end to the other end.
