Kaolin

Kaolin

  • Kaolin Clays are inert hydrous aluminum silicate clays with a low shrink-swell capacity, low cation-exchange capacity, and minimal grit content, well-suited to a wide range of industrial uses.
  • Active Minerals International produces the Acti-Min® line of air-floated kaolin clays, along with other specialty and private labeled air-float kaolin clays.
  • Applications for Active Minerals Internationals line of Acti-Min kaolin clays include:
    • Raw material for production of Fiberglass, Refractories, Cement, and Catalysts
    • Filler for Rubber, Ceramics, Roofing, Caulks, Sealants and Paints.
  • Active Minerals International’s Kaolin Clays start from high purity clay deposits. They are further refined by milling, air-classification, and blending. All kaolin clays produced by Active Minerals are “air-float” clays, avoiding the use of dispersants that can alter performance in some applications. Production is carried out according to rigid ISO 9001:2008 certified quality processes and testing to ensure highly consistent products that meet specific product requirements for many industrial applications.

At AMI, we have kaolin facilities that produce both hard and soft clays. Our Gordon, GA facility produces “soft clay” which is air float kaolin. Our Aiken, SC facility produces “hard clay” which is a reinforcement clay.

Air float kaolin is used as a raw material in the fiber glass and ceramic industries. It is also used as a filler in the asphaltic roofing, rubber, adhesive, agricultural, construction and paper industries. Our soft kaolin products and their applications include the following.

ACTI-MIN® SA-1
Used in soft rubber applications which include: Computer mouse pads, automotive floor mats, toilet plungers, gaskets, bath mats, floor tiles.
Our hard clay products are used in automotive hoses and belts, shoe soles, wire and cable, rubber tires for lawn equipment, garden hoses, rubber floor mats and tiles. (Crown®, Crown White®, Champion®)
