Products

Amtal for Ceramics
Applications include: Wall and floor tiles, table ware, sanitary ware, electric insulators, porcelain, hobby ware, technical ceramics, and steatite ceramics.
Amtal for Paints and CoatingsIn addition to the ceramic talc mines, American Talc owns and operates mines with whiter, platy talcs that are widely used in industrial primer and exterior finishes. These talcs improve flatting, leveling, brushing ability, and suspension properties while reducing gloss.

Talc is an economical replacement allowing a reduction in pigment costs. Talc has rust inhibiting and corrosion resistant properties, which helps produce improved installed life and provides superior finishing paints.

Amtal for Plastics
Talc is widely used in the plastics industry as an inexpensive filler and it adds desirable traits to various plastic products. Some of talc’s traits in plastics are listed below.

– Talc improves the tensile strength and dimensional stability of all types of plastics.
– Talc improves the thermal and electrical resistance of plastic products
– Talc is chemically inert and improves the chemical resistance of the plastic.
– Talc reduces the abrasiveness for handling and lowers the cutting costs in production.
– Talc improves the UV resistance and increases outdoor life in many plastics.
– Talc reduces the weight of plastic when compared with limestone fillers.

Many American Talc plastics customers have used American Talc products for over 25 years. These talcs provided very effective lower cost options where high purity talc of lower brightness can be used. The automotive plastic industry, the wood composite industry, the recycle plastic for lawn furniture, and railroad ties industries are examples of existing and new customers who are using more cost effective talcs.
