The WHS series ultrafine acicular wollastonite powder demonstrates significant application value in both polymer and paper industries.In polymer applications, when incorporated into resins including PA, PP, and PE, it remarkably enhances physical properties while expanding application scope. Its superior electrical, mechanical and thermal characteristics enable reduced consumption of expensive colorants without compromising product quality. The low thermal expansion coefficient ensures minimized mold shrinkage and improved dimensional stability, while its high hardness and aspect ratio effectively boost product hardness and mechanical performance.For paper manufacturing, owing to its high refractive index and whiteness properties, this premium filler material significantly improves paper opacity and brightness.
