Product Description
This material is based on chlorinated polyethylene and mixed with other additives. It has heat resistance, flame retardancy, oil resistance, wear resistance, cold resistance, weather resistance, and excellent mechanical properties. Equivalent to the XH-03A type sheath in GB7594-87 standard, which is a 90 ° C heavy-duty non flammable rubber sheath. Due to its excellent performance, good extrusion appearance, good flexibility, and suitable cost, it has become an ideal substitute for rubber sheath materials based on chlorosulfonated polyethylene rubber.
Product Usage
Suitable for the outer sheath of medium and high voltage rubber sheathed cables, it has excellent heat resistance, ozone resistance and other characteristics. It has good flame retardant properties and can directly replace the heat-resistant, weather resistant, and flame-retardant rubber sheath made of chlorosulfonated polyethylene as the base material in traditional products. At the same time, it has better mixing and extrusion process performance than chlorosulfonated polyethylene rubber sheath material and is easier to store.
