产品名称NAME：Wollastonite (硅灰棉)
产品描述PRODUCTION DESCRIPTION：
Wollastonite can be used to make brake pads, ceramic glazes, etc., and is widely used in industrial production such as automobiles, metallurgy, ceramics, and plastics. Among them, the most promising field of wollastonite consumption in the world is the engineering plastics industry. As a filler and reinforcing agent in the plastic and rubber industry, wollastonite is increasingly replacing metal parts in industrial products, and the market demand for it increase rapidly.
