Imerys, Transform to perform

Rubber

Imerys Kaolin is a major supplier of calcined kaolin's, silane treated calcined kaolin's, hard and soft kaolin's to the Global rubber cable industries. Strong technical understanding of our products and their applications in rubber complements the natural value of the minerals we supply.

Imerys Kaolin investment in product and application development is a clear commitment to our customers in the rubber industry.

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 rubber 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, improve mechanical and electrical properties. IMERYS kaolin's 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.

Fully calcined kaolin can be treated with functionalized silane to give a particle surface capable of chemically coupling with the polymer. Filler dispersion is also improved. Due to the reduced surface activity, calcined kaolin's give good reinforcement and permanent set properties, maintaining very good processability.
