Talcum powder used in plastic resin modified rubber dies, rolling, extrusion, injection, such as processing performance, and some of the more expensive replacement of (rubber) 10-15% to reduce the cost of raw materials and its properties.2. In the paint, coatings, the sun-resistant, anti-high temperature, ultraviolet light is not in color, long-term to maintain the original luster and color, there is a better performance of acid corrosion, and good water resistance, anti-pollution , anti-aging properties of a strong, wear-resistant, resistant to steam and chemical stability, and more flame-retardant properties.
