Product Description
This material is based on chlorinated polyethylene and mixed with other additives and pigments. It has flame retardant, oil resistant, wear-resistant, tear resistant, cold resistant, weather resistant, bright and durable colors, and excellent mechanical properties. The performance exceeds the XH-03A sheath specified in GB7594-87 standard. Due to its excellent performance, good extrusion appearance, good flexibility, light cable weight (low density), and low cost, it has become an ideal substitute for chloroprene rubber and chlorosulfonated polyethylene rubber as base rubber sheaths.
Product Usage
According to GB12972-91 and MT818-2009 standards, mining cables are classified by the color of the sheath to determine the voltage level. Our company produces CPE yellow and red sheaths suitable for mining 0.66/1.14Kv and 3.6/6Kv cables, respectively. Its color is bright, long-lasting, smooth and flat in appearance, and its mechanical properties are good, far exceeding traditional chloroprene rubber colored sheaths.

Processing process parameters
It is recommended to use CV (continuous vulcanization) production for extrusion production.
Extruder compression ratio: 1.1:1-1.5:1;
Length to diameter ratio: 6:1-16:1 (hot feeding is recommended for ratios below 10:1);
Extruder temperature: 65-85 ° C;
Sulfurization tube temperature: 165-185 ° C.
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.
