Product description: DCSH 21A CPE Cable Jacket Compound (Fire retardant Thermoplastic Compound under the temperature at 85℃) Ⅰ.Illustration With Chlorinated Polyethylene (here below called CPE), blended with other additives, DCSH21A Jacket has excellent properties of fire retardancy, wearing-proof, tearing-proof, cold-resistance, weathering-resistance and excellent mechanical properties. It is equivalent to ST2 type thermoplastic Jacket according to IEC60092-359 standard, say flame retardant thermoplastic Jacket Compound and meets UL1581-2001 standard. With its excellent properties, excellent extruded surface, lower density & lower cost, our DCSH21A is the best ideal substitution of fire retardancy & heat-resistance PVC products and its relevant products. Ⅱ.Application It is mainly used for the Jacket material of CATV cable, power limiting electric circuit cable, power limiting warning electric circuit cable, etc. It also has outstanding properties of weather-resistance, UV-ray-resistance, etc. So, it is can be also used for Jacket material of shipyard electrical cable and control cable under temperature at 85℃.
