1. The thermoplastic tube is a thermoplastic tubular material, also called the thermoplastic tube, some people also called thermoplastic tube. It is widely used in electronic, electric, electrical, mechanical and other industries. It is mainly used for insulation and protection, but also for various other uses, such as decoration. So for different applications, there are different materials of the thermal shrink casing. The so-called material is actually a comprehensive material formula, including a variety of materials, mainly the main materials, flame retardants, plasticizers, antioxidants and so on. The main material, of course, is the material that determines the main properties of the tube, and the auxiliary material can increase or increase some properties, so when we talk about the material of the heat casing, it actually means the main material. According to the current product series, the main materials can be divided into PE polyethylene heat shrink casing, PVC heat shrink casing, PET heat shrink casing, Tieflon heat shrink casing, EVA heat shrink casing, rubber heat shrink casing and other new materials heat shrink casing and so on.Some people also say that polyolefin thermal condensation casing, polyester thermal condensation casing, in fact, these two are a general term, olefins and esters are a large category of chemicals, such as our polyethene, polyvinyl chloride is a polyalkene, PET is a polyester. There are, of course, differences, even if they are also polythene thermosetting, because polyethylene is divided into many categories, such as HDPE, which has only a small number of short chains. Low density polyethylene(LDPE) molecular chain is a large number of long chain branched; Linear low density polyethylene(LLDPE), not containing long chain branched, but containing short side branched, "linear" means no long chain branched .
In the industry, the shrinkage ratio is 2: 1, 3: 1, 4: 1.
2. If it is specific to the type of shrinkage ratio, it is specific to the use of the product, such as: you need to fit the size of the diameter of the product, simple use, the thermal shrinkage ratio is not required.
The size of the tube is usually the product of multiplying the maximum diameter of the tube with the shrinkage.
3. Hot shrink sleeve is a special polyolefin material heat shrink sleeve, or EVA material. The outer layer is made of high quality and soft crosslinking polyolefin material and inner layer hot melt adhesive. The outer layer has the characteristics of insulation, corrosion prevention, wear resistance, and the inner layer has the advantages of low melting point and high adhesion of waterproof sealing box.
