Gecalcineerde Kaolien

Calcined Kaolin is an anhydrous aluminium silicate produced by heating ultrafine natural kaolin to high temperatures in a kiln. The calcination process increases whiteness and hardness, improves electrical properties, and alters the size and shape of the kaolin particles.

PoleStar™ 200P is a very effective opacifying extender in paint, partially replacing TiO2and reducing the overall cost of paint formulations while maintaining paint film quality.

When formulated into film compounds calcined kaolin improves the thermal properties of agricultural films, giving the potential to reduce heating costs, reduce the planting to cropping time and increase the length of the growing season. In film that requires antiblock additives, calcined kaolin offers an ideal and cost-effective balance of antiblock, haze and clarity performance.

In plastics calcined kaolins are used in PVC cables to improve electrical performance and in its coated form (like Polarite™ 102A) as a functional filler in engineering thermoplastics.

Recommended applications for Calcined Kaolin:

  • Paint & Coatings
  • Plastics & Polymers
  • Rubber
