Product Lines

We offer a wide range of products throughout the world, differing in shape factor, particle size distribution and brightness to suit all paper application needs.


The Platinum™ product line is specially designed to be used in coatings for silicone release base papers, where it provides excellent coating coverage and low sheet porosity to improve silicone hold-out. High natural purity and specialized processing minimize any compounds that can adversely affect silicone curing processes that use platinum catalysts.


Therma-Print is a calcined kaolin for direct thermal and thermal transfer paper coatings designed to improve coating coverage, control ink absorbency and improve thermal print properties.

Diatomaceous earth (DE) and silicon carbide

Diatomaceous earth (DE) and silicon carbide are used in friction papers to gain a controlled level of surface roughness. Applications include friction paper for auto transmissions and clutches.


We offer a full range of bespoke formulation and technical and process support services to help you match the right mineral grade to your application requirement.
