Product Description

Common calcined kaolin for Wire and Cable

1. Benefits and Application

GB-CK90S is an anhydrous aluminum silicate produced by a controlled, high-temperature heating of a water-fractionated kaolin.
During calcination, chemical, morphological and mineralogical changes occur.
GB-CK90S imparts excellent electrical insulation properties to low and medium voltage power cables.
