Where can these Kaolin products be used?

Ultrafine kaolin semi-reinforcing fillers are used in a wide variety of rubber applications. Calcined kaolin and surface treated calcined kaolin improve mechanical and electrical properties. Our range includes grades for use at all voltage levels of cable insulation compound. 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.

Product trade names and descriptions

The below descriptions provide a general insight into our product range on offer from Imerys.

There are a few exceptions where unique products don’t conform to the standard nomenclature, for accurate product information, please search for corresponding technical data sheets via our product finder.

  • Agribind

    A naturally occurring alumino-silicate sold extensively into the animal feed industry to have a favourable effect on the welfare of animals.

  • Barrisurf

    Barrier kaolins have hyper-platey, nano-dimensional thickness crystals which create a tortuous coating structure that inherently resists penetration.

  • Devolite

    Specially designed pre-dispersed china clay with an alkaline pH, reducing the need for deflocculants

  • Hexafil

    A secondary finer particle size ball clay, pH controlled, low cost and provides more reinforcement than kaolin, used in the shoe soling and rubber floor mat industry

  • Hydrite

    A fine particle size, pH neutral hydrous kaolin with a medium binder demand suitable for solvent and water based coatings

  • Hymod

    Providing excellent processability these ball clays are used in construction and rubber

  • Hyplas

    Providing excellent processability these ball clays are used in construction and rubber

  • Hywhite

    Providing excellent processability these ball clays are used in the rubber industry

  • ImerPrint

    An ultra-fine hydrous kaolin extender designed to extend TiO2 and maintain high gloss of printing inks and varnishes

  • ImerSilk

    A fine kaolin extender for decorative semi-gloss and silk paints

  • InFilm

    An ultrafine, selectively controlled calcined kaolin, giving excellent antiblocking properties

  • Metastar

    Pozzolanic metakaolin, highly reactive material making it particularly suitable to enhance the performance properties of concrete products

  • Molochite

    Calcined kaolin used in investment casting, kiln furniture and general refractory industries (quartz, cristobalite and nodular iron free)

  • NeoGen

    An engineered calcined kaolin designed to provide excellent optical performance in flat/low sheen interior and exterior architectural coating applications

  • Opacilite

    High whiteness calcined kaolin produced by a special rapid heating process which creates a large number of tiny voids within the kaolin particles, resulting in a low specific gravity and outstanding opacifying properties

  • OptiGloss

    An ultrafine kaolin extender for decorative gloss paints

  • Polarite

    Calcined kaolin treated with a vinyl functional silane for use with polyamides, peroxides and other radical cross-linking systems

  • PoleStar

    A variety of dehydroxylated aluminium silicate grades produced by heating highly refined kaolins to high temperatures

  • Polsperse

    An ultrafine kaolin produced by a high intensity pulverisation process, specifically designed for use in solvent-based paints

  • Polwhite

    High quality, medium particle sized natural kaolins produced in the UK

  • Speswhite

    Highly refined kaolin of ultrafine particle size and high brightness produced in the UK

  • Stockalite

    Specially designed pre-dispersed china clay with an alkaline pH, reducing the need for deflocculants

  • Supreme

    Highly refined kaolin of ultrafine particle size and high brightness produced in the UK
