Product Description
This material is based on chlorinated polyethylene and mixed with other additives. It has excellent flame retardancy, low temperature resistance, low smoke, earthquake resistance, radiation resistance, and outstanding mechanical properties. It is an ideal substitute for rubber sheaths based on chloroprene rubber and chlorosulfonated polyethylene rubber. This product fully meets the technical requirements of GB/T29631-2013 standard and can also adapt to the special working environment of wind power plants.
Product Usage
Suitable for single core wind energy flexible cables with ethylene propylene insulation and chlorinated polyethylene sheath for AC rated voltage of 1.8/3kv and below.

Processing process parameters
It is recommended to use CV (continuous vulcanization) production line for extrusion production.
Extruder compression ratio: 1.1:1 to 1.5:1;
Length to diameter ratio: 6:1 to 16:1 or higher (hot feeding is recommended for ratios below 10:1);
Extruder temperature: 65-85 ℃;
Sulfurization tube temperature: 165-185 ℃.
Packaging and Storage
The material has a rectangular film shape (which can also be packaged and changed according to user requirements), and should be stored in a clean, dry, and ventilated warehouse.
