Rubber
We offer a vast portfolio of functional additives to enhance the properties of rubber and elastomer compounds.
Functional additives for enhanced rubber
Our portfolio of functional additives enhance the properties of rubber and elastomer compounds. Our mineral additives include air- float kaolin, ball clay, calcium carbonate, diatomite, hydrous and calcined kaolin, mica, wollastonite, carbon black, graphite and talc*.
Our minerals are key ingredients in rubber compounds for the production of a wide range of end products such as tires, flooring, medical gloves, industrial and consumer goods, cables and pharmaceutical stoppers. They improve processability, barrier properties, electrical properties, fire resistance, compression set and tear resistance.
We refine and engineer these minerals through proprietary processes that influence their chemical and physical properties, including size, shape, structure and surface chemistry, to obtain the exact properties our customers require while optimizing the cost-performance ratio in their final products.
Our minerals improve the dispersion of reinforcing fillers to reduce mixing time. They improve barrier performance and enable the downgauging of end applications like medical gloves and tire inner liners, thus contributing to better productivity.
*Talc products are not available in the USA and Canada. Contact us for an alternative range.
Key benefits
Imerys Kaolins de Bretagne in southwest Brittany hosted an open day to commemorate its 120th anniversary, bringing together the general public, site employees and their families, customers, representatives of local associations, local elected officials and other important regional stakeholders. The day also marked another significant milestone for the company's future, since it coincides with the renewal in 2023 of the prefectural order authorizing Imerys to continue its mining activities at Kaolin de Bretagne for a further 28 years.
Calcined clay and talc provide the properties essential for the manufacture of secure and reliable rubber medical stoppers.
Imerys is supporting medical glove manufacturers to meet increased demand in the healthcare market.
