The so-called material is actually a comprehensive material formulation, including a variety of materials, mainly mastering the mother, flame retardants, color mother, plasticizer, antioxidants and so on. Of course, the main material is to determine the main performance of the heat shrink tube material, auxiliary material can increase color or increase some performance, so when we call the hot casing material, in fact, refers to the base of the heat shrink tube, that is, the main raw material of the heat shrink tube.
According to the current product line, the main material can be divided into PE polyethylene heat shrink sleeve, PVC PVC heat shrink sleeve, PET heat shrink sleeve, TFE heat shrink sleeve, EVA heat shrink sleeve, fluoro-rubber heat shrink sleeve, triple ethyl propylene heat shrink sleeve, silicone Rubber-type heat shrink tube and other new material scallishrink casing and so on, PE, PVC, etc. are chemical abbreviations, and some people will say polyolefin heat shrink sleeve, polyester shrink sleeve, in fact, these two are a common name, olefins and esters are a large category of chemicals.
