Therefore, there are different materials of heat shrinkable casing for different purposes. Mainly for insulation, protection, but also a variety of other uses, such as decoration. Of course, the main material is the material that determines the main function of the heat shrinkable tube, and the auxiliary material can increase or increase some functions, so when we talk about the material of the hot sleeve, it really refers to the main material. Let's leave it at this point, friends generally know this is ok, further will need more professional knowledge and background.
A heat shrinkable tube is a thermoplastic tubular material, also known as a heat shrinkable tube, or thermoplastic tube by some people.
Each type of polyethylene also has a different function.
So-called material is actually a kind of comprehensive material formula, including a variety of materials, main material, flame retardant, plasticizer, antioxidant and so on.
It is widely used in electronics, electric power, electrical, mechanical and other industries.
Of course, even if the same belongs to polyethylene heat shrinkable casing, there are differences, because polyethylene is divided into many kinds, such as high density polyethylene (HDPE) molecular chain only a small amount of short chain branch; Low density polyethylene (LDPE) molecular chain is a large number of long chain branched; Linear low density polyethylene (LLDPE), does not contain long chain branches, but contains short side chain branches, "linear" means no long chain branches.
According to the current product line to see main ingredient can be divided into PE PE heat shrinkable sleeve, PVC PVC heat shrinkable casing, PET heat shrinkable sleeve, teflon heat shrinkable casing, EVA heat shrinkable tube, rubber hot shrinkage and other new materials heat shrinkable casing pipe and so on (PE, PVC, etc are chemical abbreviation for short, not clear friend can check chemical dictionary). Some people will say what polyolefin heat shrink tubing, polyester heat shrink tubing, in fact, these two are a general term, alkenes and esters are a major class of chemical substances, such as our polyethylene, POLYvinyl chloride belongs to polyolefin, PET belongs to polyester.
