Spiral protective sleeve flame retardant type, the use of hot winding shaped extrusion process made of spiral sheath.

It has the following features and advantages:

• Flame retardant performance: has passed UL94,/V0/V2 level can effectively prevent the spread of flame, reduce the risk of fire.

Good wear resistance: can reduce the external friction on the internal product wear.

• UV: in the outdoor environment can effectively resist the erosion of ultraviolet rays.

• Anti-aging: delay the aging process of the product and extend the service life.

• Corrosion resistance: It has strong corrosion resistance and can protect internal products in different chemical environments.

Its wide range of applications, commonly used in coal mine support, wire and cable, fear of fire, hydraulic hose, wire, cable and other products of the external. After installing the spiral protective sleeve, it can not only improve the overall appearance, but also extend the life of the internal product by more than 3 years.

The flame-retardant spiral protective sleeve is easy to install, with better wear resistance and aesthetics; it has strong aging resistance and corrosion resistance, and can more effectively protect the outer surface of hydraulic hoses, wires, cables and other products against aging and friction; At the same time, it has more excellent, more convenient, more environmentally friendly and energy-saving effects.
