Uses Of Modified Talcum Powder


Talc can be widely used in PP, PE, PS, PA, ABS, PC, PVC and other products. Talcum powder filled plastic can improve the rigidity, dimensional stability, and lubricity of the product, prevent high-temperature creep, reduce the wear on the molding machine, and enable the polymer to increase the hardness and creep resistance through the filling, and the impact strength Basically unchanged.


Talc has good suspension and dispersibility, and low abrasiveness. As a filler for coatings, talc with flaky particle structure can make the coating film have high water resistance and impermeability of enamel paint. It is mainly used in primers. Lacquer and intermediate coating; talcum powder with fibrous particle structure, because of its high oil absorption and good rheology, the storage stability of the coating is improved. And the rheology and leveling of the coating can be well improved. At the same time, the weather resistance of the coating can be improved.

3.Paper making

Talc has unique properties such as layered structure, softness, and hydrophobicity, and has significant advantages when applied to the paper industry:

Helps increase filler retention and improve paper opacity, smoothness and printability, giving paper higher ink absorption;

The surface is hydrophobic, and organic matter is easily adsorbed on the talc layered surface, which reduces the consumption of dyes and effectively saves costs. In addition, its lipophilicity makes it useful as a resin, adhesive inhibitor and waste paper deinking agent;

It can be combined with sizing agent well to improve sizing agent retention, and can reduce the absorption of the paper, and prevent the printing ink from penetrating the paper;

Talc powder has a low friction factor, which can make the surface of the coating smooth and soft, which can reduce the breakage of the coating and reduce the printing pressure;

Talc has special lubricity. The coated paper made from it can obtain high finishing degree on the calender, and can reduce the amount of lubricant in the coating.
