				| PoleStar 450 |  |  |  | Aluminum silicate |  |  |  | Aluminum silicate |  |  |  | 1332-58-7 |  |  |  | PoleStar 450 is a dehydroxylated aluminum silicate produced by a controlled, high temperature heating of a water-fractionated kaolin. PoleStar 450 was specifically designed for use as a filler in polyvinyl chloride electrical insulation.
 PoleStar 450, predominately meta-kaolin, greatly improves the volume resistivity of polyvinyl chloride insulation compounds under both wet and dry conditions.
