kaolin in wire and cable processing applications: Kaolin functional additives are also a large number of applications in the processing of wire and cable, especially for EPDM cable. Sheath material of ordinary wires and low voltage cables (1 2KV) with PVC and PE resin, unless to flame retardant requirements generally do not need filler, sometimes adding calcium carbonate to reduce the cost and improve the dielectric properties. EPDM and XLPE materials are mainly used in high voltage cable (15--33KV). XLPE generally do not need filler. For industrial market, 90% of EPDM cable, requiring high physical and mechanical properties of the cable and need high performance of filler, in order to meet the use requirements.
