How much do you know about customized Heat Shrinkable Sleeve?

2021-05-11 15:46

A customized Heat Shrinkable Sleeve is a sleeve made of heat shrinkable material. It is divided into many types according to the material, such as polyethylene type, PVC type, PET type and so on. The customized Heat Shrinkable Sleeve without special indication of the material below refers to the type of radiation cross-linked PE.
The heat-shrinkable material is glassy at room temperature and becomes highly elastic after heating. During production, the material is heated to a highly elastic state, a load is applied to make it expand, and it is rapidly cooled while maintaining the expansion, so that it enters the glass state, and this state is fixed. When heated during use, it will return to a high elastic state, but when the load is gone, it will retract.


customized Heat Shrinkable Sleeve: The above-mentioned polymer or polymer alloy is extruded to obtain a tubular intermediate product of a specified size, and the tubular product with a certain size obtained by irradiating (or chemical) cross-linking is heated and expanded, and cooled and shaped into a tubular product with a certain size. customized Heat Shrinkable Sleeve.
Halogen-free flame-retardant heat shrinkable material: Add a certain amount of non-halogen, heavy metal and other harmful flame retardants to the heat-shrinkable material to meet certain flame-retardant requirements and environmental protection requirements, and it will become halogen-free flame-retardant heat shrinkable material.
Irradiation: A chemical technology that uses radiation from radioactive elements to change the molecular structure.
Cross-linking: Make a linear polymer into a polymer with a three-dimensional network structure. Combining radiation cross-linking technology and flame retardant technology, the resulting cable material has excellent flame retardancy, high heat resistance, and excellent physical and mechanical properties.
The above is an introduction to the knowledge of what is a customized Heat Shrinkable Sleeve, I hope you can learn more.
