Due to its unique acicular structure, it can be used in fiber-reinforced polymers and engineering plastics to replace glass fibers. Improve the flexural strength and flexural modulus, heat resistance, mechanical properties, scratch/wear resistance and dimensional stability. Reduce shrinkage of materials and warpage of rates. Superior properties of thin-wall molding, to replace short-chopped glass fibers, asbestos fibers and other synthetic fibers, to save cost and to protect the environment, to improve the surface appearance of the products. Reinforced composites filled with acicular wollastonite can be recycled. Modified wollastonite does not fade under long-term exposure, which is mainly used in ? the chassis of computers and DVD disks, auto parts and resin, the shell of household appliances, the plastic and rubber products and the flank of the tyres.
