Product features
3.Product features
The product has high whiteness and uniform particle size. In the coating, talc powder serves as a filler, which can act as a skeleton, reduce manufacturing costs, and improve the hardness of the coating film. It can mainly increase the stability of product shape, increase tension strength, shear strength, bending strength, pressure strength, reduce deformation, elongation rate, thermal expansion coefficient, strong dispersibility and other characteristics.
Adding talcum powder to plastics can improve the rigidity of products, enhance dimensional stability, prevent high-temperature creep, increase fire resistance, acid alkali resistance, electrical insulation, and have lubricity, reducing the wear of molding machinery or grinding tools. Mainly used in plastics such as PVC, PP, PA, ABS, PE, PS, etc.
Talc powder is mainly used as an isolation agent and surface treatment agent in rubber, and can also be used as a filler. It is mostly used in acid, alkali, and heat-resistant products, and has a certain reinforcing effect on synthetic rubber.
