Generally used as extender when more plastic filler. Demand has the following characteristics: (1) chemically inert; (2) on the water resistance, chemical resistance, weatherability, heat resistance without hindrance; (3) does not reduce the physical properties; (4) a filling; (5) low density; (6) price.
