POLESTAR™ 200R

Calcined clay widely used in the rubber and polymer industries. It allows for excellent extrusion in hoses and gaskets. It is used in automotive car door seals & hoses, O-rings, membranes, cable sheathing & insulation and FR cables. It is also used in hydraulic & industrial hoses. It is produced by heating highly refined kaolins to temperatures above 1000°C. Benefits:Provides low compression set for rubber seals and stoppersImparts excellent electrical insulation properties to low and medium voltage power cablesDisplays low moisture pick-up and good thermal aging resistance (air or water hoses)Offers high brightness, low dissipation factor and low moisture pick-up

POLESTAR™ 400

Structured aluminum silicate suitable for automotive car door seals & hoses, gaskets and membranes. It is also used in cable sheathing & insulation, FR cables and hydraulic & industrial hoses. It is produced by a controlled, high temperature dehydroxylation of a precisely fractioned and ultra-fine particle kaolin.Benefits:Offers reduction of electrical conductivity/corrosion, surface finishing & low compression setDisplays low moisture pick-up and good thermal aging resistance (air or water hoses)Provides high brightness, electrical insulation & low dissipation factor

POLESTAR™ 501

Calcined kaolin-based filler developed for EPDM cable insulation and light-colored extruded rubber profiles. It is suitable for the production of rubber cable sheathing of flexible cable.Benefits:Provides electric insulation in low and medium voltage power cablesExhibits improved compression set

SPESWHITE™

Highly refined kaolin suitable for cable sheathing, and hydraulic & industrial hoses. It is produced from deposits in the Southwest of England.Benefits:Possesses ultrafine particle size and high brightness Offers abrasion resistance and adhesion to metal

SUPREX™

Hydrous clay suitable for automotive hoses & tires, cable sheathing and shoe soles. It is also used in hydraulic & industrial hoses. Benefits:Displays gas permeability reduction, abrasion resistance and adhesion to metal
