What is a heat shrink tubing?
Heat shrinkable tubing, as the name suggests, is a type of tubing that shrinks when heated. The polymer is made of polyolefin as raw material and cross-linked by irradiation, which has good heat resistance and mechanical properties. With the increase of temperature, the diameter of the heat shrinkable tube decreases, and its length is basically unchanged, and some heat shrinkable tubes with better shrinkage can reach 3 times to 6 times the shrinkage, so it is widely used in the fixing and protection of various wires, cables, pipes, etc.
Properties and benefits of heat shrink tubing
Shrinkage: Heat shrinkage performance is an important characteristic of heat shrink performance. At the right temperature, the heat shrinkable tubing can be closely attached to different sizes of items to form a tight protective layer, which can reach at least 2 times the shrinkage amount, and some can even be 6 times the shrinkage of the tubing.
Heat resistance: Heat shrink tubing has excellent heat resistance characteristics and is able to maintain the stability of its performance at higher temperatures. As a result, it is widely used in automotive, aerospace, power, and electronics.
Insulation: Made of polyolefin-based plastic, it has excellent insulation, and can play a good role in protecting indoor lines and pipelines.
Flexibility: The heat shrinkable tubing has good elasticity, can form a smooth protective layer at the curved surface and corners, and can ensure the tightness and durability of the product.
Environment: The heat shrinkable tubing can be recycled, which reduces the pollution to the environment.
