Rubber

IMERYS is a major supplier of high quality minerals to the rubber industry throughout the world.
Our portfolio for rubber includes ultrafine kaolin, calcined kaolin, surface treated calcined kaolin and ball clay.

Calcined kaolin offers superior reinforcement, excellent extrusion and compression set, all important properties to the designer of rubber compounds and articles. Calcined kaolin is chemically inert and our grades have low heavy metal content properties which are beneficial when making pharmaceutical stoppers.

Kaolin offers semi-reinforcing properties in most types of rubber compound, offering the formulator an alternative to more expensive synthetic materials. Kaolin also gives barrier properties which are beneficial when formulating compounds for hoses and gaskets.

Ball clay, offers more reinforcement than Kaolin, as a result of it’s finer particle size. Often referred to as hard clay, it gives excellent compression set and abrasion resistance. A common application for ball clays is in the shoe soling and rubber floor mat industry.

All of our products are supported by a high standard of technical service, product development and research from a team of highly experienced scientists and specialists in the rubber industry.
