Industrial Grade Talcum Powder High Whiteness Talc Powder 1250mesh For Coating, Rubber, Ceramics, Plastic
Unique Properties
Product Description
The main component of talc is magnesium silicate with water content of talc, and its molecular formula is Mg3[Si4O10](OH)2. Talc belongs to monoclinic system. The crystal is pseudohexagonal or rhombic, occasionally seen. They are usually compact, massive, leaflike, radial and fibrous aggregates. It is colorless, transparent or white, but it is light green, yellow, brown or even light red due to a small amount of impurities; the cleavage surface is pearl luster. Hardness 1, specific gravity 2.7-2.8.
Characteristic
Talcum powder has excellent physical and chemical properties, such as lubricity, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good covering power, softness, good luster, strong adsorption, etc. Because the crystal structure of talc is layered, it has the tendency to split into scales and special lubricity.
Certificate
Our factories have achieved ISO Certificate, 23 technologies have obtained national patents.
Application
1. Chemical grade
It can used in rubber, plastic, paints and coatings and other chemical industries. As fillers, it can increase the stability of product shape, increase tensile strength, shear strength, winding strength, pressure strength, reduce deformation, elongation, thermal expansion coefficient, high whiteness, particle size uniformity and dispersion.
2. Ceramic grade
It can be used for making high frequency porcelain, wireless electric porcelain, various industrial ceramics, architectural ceramics, daily-use ceramics and ceramic glazes, etc.
3. Cosmetics grade
It is a good filler for the cosmetic industry. Contains a large amount of silicon. It has the function of blocking infrared ray, so it enhances the performance of sunscreen and anti-infrared ray of cosmetics.
4. Paper making grade
It can Used for all kinds of high and low grade paper industry products. Characteristics: paper making powder has the characteristics of high whiteness, stable granularity and low abrasion.
5. Medical food grade
Additive used in medicine and food industry. Features: non-toxic, tasteless, high white, good tolerance, strong gloss, soft taste,smooth features.
6. Super fine talcum powder
Used for high-grade paint coating, plastic, cable rubber, cosmetics, copper paper coating, textile lubricant etc.
