Wollastonite powder has been used in vulcanized rubber, asphalt vinyl brick, vinyl resin, polyepoxy vinyl plastic board, phenol model. In the production of epoxy resin, 50% wollastonite powder is used as filling agent, which has the characteristics of low water absorption in the non-solidified state. Wollastonite can improve the properties of polymers and act as a filler for elastic materials, which can lower the price. The synthetic material has high thermal stability, low dielectric index and water absorption, and stable mechanical properties.
