Cimbar Performance Minerals intermediate Polyfill series alumina trihydrate products are specially produced for thermoset plastic/CASE applications that require high loading levels. Compounders using intermediate Polyfill series products are able to achieve maximum loading levels with acceptable physical properties. The increased loading levels with use of intermediate Polyfill series products increases flame retardancy and smoke suppression with more H2O molecules available. Polyfill/PolyJet alumina trihydrate products are tightly controlled by Cimbar Performance Minerals ISO 9001:2015 quality program.
