Material Notes:
Calcined clays, such as Polyfil® 70, are brighter than most water-washed clays, offering excellent processing and limited reinforcement. They impart outstanding wet/dry electrical properties due to the elimination of bound water during the calcined process. Compounds with calcined clays extrude smoothly and reduce stickiness in processing. Polyfil® 70 is a high brightness calcined kaolin clay used to extend elastomeric and thermoplastics products, including wire and cable applications.Industry: Rubber & PlasticUses: Non-Black Rubber, General Rubber Goods, General Plastics, Polyolefins/PVC, Thermoset, Thermoplastic, EPDM, Wire & CableInformation provided by KaMin LLC.
