Description

Talcum powder is a type of talc within magnesium silicate saline mineral talc group. Its major composition is magnesium silicate that contains water, which shows to be silicon dioxide and magnesia; Talcum belongs to monoclinic crystal system. The crystal appears to be pseudohexagonal or rhombic flake, and it often appears to be compact block, vane, radiation or fiber shaped aggregation in general. It is colorless and transparent or white, but it may display light green, light yellow, light brown or even light red as it contains a little sundries; The cleavage plane of the product shows pearl luster.

Talcum has many excellent physical and chemical properties, such as: Strong lubricating performance, adhesion resistance, flow-promotion, refractory character, acid resistance, insulation, high melting point, inactive chemical property, high hiding ability, tenderness, perfect luster and strong absorbability. As the crystal structure of talcum is stratiform, it has such trend to easily split into squama and special lubricating performance.
Talcum powder is widely applied in medical, household and personal care chemical, food, paper making, rubber plastic, paint /coating, felt, porcelain, leather making industries. It can enhance the comprehensive performance of product and reduce production cost
