Polyfil® WC-426

Treated, anhydrous aluminum silicate. Treated kaolin clay is an organo-functional pigment designed to maximize compatibility with surrounding polymers and to minimize absorption of interfacial moisture. It imparts low conductivity due to the elimination of bound water during the calcined process. Mechanical and electrical properties of polymers such as EPR and cross-linked polyolefins are preserved even after long-term exposure to a high-humidity environment. Compounds with calcined clays extrude smoothly as well as reduce stickiness in processing.
