Talc powder is an industrial mineral that has been used as a pigment and filler in paints & coating, paper making, rubber, modified plastic, ceramic, adhesive and other industries. It is mainly composed of hydrous magnesium silicate, which is processed into powder after selection, washing and crushing.
Kmeris Mineral Products is a leading producer of talcum powder in China. Our Superfine Talc Powder, Talc power F020 F017 F022 F018 F028 F023 F019 are widely used by famous international architectural paints factories world widely.
Chemical Name :
Talc Powder F017Application :
Suitable for electronic materials, marine paint, automotive paint, ink coatings, silica gel, investment casting, high-grade electrical insulation and other industries.Product model :
F017, F020, F022 F018 F028 F023 F019The main component of talc is hydrated magnesium silicate, with the molecular formula of 3MgO4SiO2H2O. Talc belongs to monoclinic system, and its crystals are pseudo-hexagonal or rhombic.
Talc micropowder is made by grinding talc ore through multiple processes such as selection, cleaning, air drying, crushing, grinding, grading, etc. It is a white powder with a greasy feeling, and has excellent physical and chemical properties such as lubricity, fire resistance, acid resistance, insulation, high melting point, chemical inactivity and strong adsorption.
Our products have the characteristics of high whiteness, uniform particle size distribution, good transparency, excellent suspension and moderate oil absorption. Widely used as filler in coating, paint, plastic, cable, ink, paper, rubber, textile and feed industries to improve the comprehensive performance of products, improve production efficiency and reduce production costs.
