Imerys Kaolin has a proven history of close technical collaboration with producers, compounders and processors that has led to an in-depth understanding of the mineral requirements of the industry.

Kaolin is characterized by its fine particle size, platy or lamellar particle shape and chemical inertness. This combination of platy shape and fine particle size results in improved processability, improved reinforcement, tensile strength, abrasion and tear strength and improved mechanical and electrical properties. Imerys Kaolins can be a cost-effective replacement for more expensive synthetic components. Kaolin also gives barrier properties which are beneficial when formulating compounds for hoses and gaskets.
