How does the addition of wollastonite enhance the mechanical properties of plastics?
The addition of wollastonite, a naturally occurring calcium silicate mineral, significantly improves the mechanical properties of plastics. When incorporated into polymer matrices, wollastonite acts as a reinforcing filler, enhancing tensile strength, flexural modulus, and impact resistance. Its needle-like microstructure provides structural support, reducing deformation under stress. Additionally, wollastonite improves dimensional stability and heat resistance, making it ideal for automotive and industrial applications. The mineral's low thermal expansion coefficient further minimizes cracking, ensuring long-term durability in composite materials. By optimizing filler content and dispersion, manufacturers can achieve superior performance in reinforced plastics.
