Burgess Icecap K™ is a high-performance calcined kaolin used as an extender for TiO₂ in coatings requiring a high Hegman grind. Its low screen residue, achieved through agglomerate removal, makes it ideal for applications in wire and cable, molded and extruded rubber, and plastic products. It offers good electrical properties, low compression set, and low water absorption.
