In the grand scheme of power transmission and communication networks, cables, as the lifeblood of energy and information transport, directly determine the safety and lifespan of the system through the performance of their insulation and sheath materials.

In industries such as electronics, power, and machinery, heat shrink tubing has become an indispensable product as a high-performance insulation and protective material.

Vitrified polyolefin cable material not only possesses environmentally friendly and safe properties such as low smoke, halogen-free, and flame retardant characteristics, but it also achieves a remarkable transformation from a flexible polymer to a hard ce

From an environmental adaptability perspective, thermoplastic low smoke halogen-free flame retardant cable material also possesses excellent resistance to ultraviolet aging.

Under high-temperature operating conditions, cross-linking bonds may break due to thermal oxidation or electrical stress, leading to a decrease in the degree of cross-linking.

The sheath material must have good cold resistance and impact resistance to protect the internal insulation layer from the influence of the external environment.
