Imerys supply a range of minerals from natural mined products to high-performance specially engineered minerals

Imerys’ multi-mineral group, has extensive “know-how” of a range of minerals, allowing us robust capabilities to offer combined mineral solutions to our customers including Calcium Carbonate, Kaolin, Mica, engineered mineral products derived from Diatomaceous Earth and expanded Perlite. These minerals are mined from extensive, high quality, naturally occurring reserves and is processed to develop solutions that improve product performance and manufacturing efficiency in several industries. Imery’s absolute commitment to quality ensures consistency and reliability across their products and services for an array of applications.

Where can these minerals be used?

Calcium Carbonates are used as extenders and functional fillers in the plastics & film, rubber, adhesive and coatings markets. A wide range of engineered mineral products derived from Diatomite (also called Diatomaceous Earth or D.E.) and expanded Perlite are used in a host of applications due to their highly unique diatomic structures and low densities, including filtration for liquid/solid separation. Kaolin is used as a semi-reinforcing filler in a wide variety of rubber applications, it’s used to improve mechanical and electrical properties in cable insulation. In the plastics sector, kaolins are used extensively as anti-block and infrared barrier additives in plastic films. In coatings and inks a range of super-dispersible, calcined, FCC and hydrous kaolin minerals enable the modification of important paint properties such as whiteness, opacity, gloss, rheology, stability and stain resistance. As well as controlling paint quality and performance, these minerals can also deliver significant TiO2 savings through formulation extension. Imerys’ state-of-the-art technology centers harness the intrinsic properties of Muscovite and Phlogopite Mica’s to provide solutions for industries such as plastics, rubber, coatings and construction. Their range includes extenders and functional fillers which provide good barrier effects and rheology control in various applications such as plasters and mortars, to improve mixing and trowelling properties and flexibility of finished products in construction.
