Polyfil® 80

Supplied byKaMin- Last Updated on Jul 10, 2025

Polyfil® 80 by KaMin is an anhydrous aluminum silicate. It is a calcined clay, offering excellent processing and limited reinforcement. It imparts 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® 80 is available in milled fine white powder having moderate particle size and is used to extend elastomeric as well as thermoplastics products, including wire and cable applications.
