What is the production process of Heat Shrinkable Tube?

The first is raw material preparation. The main raw materials of Heat Shrinkable Tube include Special Material Braided Sleeve, glass fiber, vulcanizing agent, accelerator, etc. The Special Material Braided Sleeve is a high molecular polymer with excellent high temperature resistance and corrosion resistance; glass fiber is used to enhance the strength and wear resistance of the material. During the production process, various raw materials need to be prepared according to formula requirements and ensure that their quality meets the requirements.

Next is rubber mixing. During the rubber mixing process, raw materials such as Special Material Braided Sleeve are put into the mixer and stirred to make them evenly dispersed. The purpose of mixing is to fully mix various raw materials to ensure that the rubber material has uniform properties to improve product quality and stability.
Next comes extrusion molding. The mixed rubber material is extruded through an extruder to shape it into a tube or other shape. Extrusion molding is a key link in the production of Heat Shrinkable Tube. It is necessary to control the temperature, pressure, speed and other parameters of the extruder to ensure that the product has accurate dimensions and smooth surface.
The last step is vulcanization. The Special Material Braided Sleeve after extrusion need to be vulcanized and cured to improve their wear resistance, high temperature resistance and other properties. Vulcanization and curing are methods such as heating or adding vulcanizing agents to cause the rubber material to undergo a cross-linking reaction, thereby enhancing its physical properties and chemical stability. The time and temperature of vulcanization and curing need to be adjusted according to specific product requirements to ensure that the product meets the design requirements.
In general, the production process of Heat Shrinkable Tube includes raw material preparation, rubber mixing, extrusion molding, vulcanization and curing. Each link needs to be strictly controlled to ensure that product quality and performance meet the requirements. As the demand for pipeline protection materials increases in the industrial field, Heat Shrinkable Tube will be more widely used and developed in the future.
