Industrial Grade Talcum Materials High Whiteness Talc Powder
The main component of talc powder is magnesium silicate, also known as hydrated magnesium silicate ultrafine powder or old powder. Due to different origins, the colors and textures vary, with pure white, silver white, or light yellow powder available. The texture is soft and smooth.
Talc powder has inactive chemical properties, but also has properties such as lubricity, high melting point, relatively acid and alkali resistance, good insulation, good covering power, softness, and good luster.
