1. Performance Enhancement: GCC significantly boosts the mechanical properties of plastic composites, including tensile strength, rigidity, and heat resistance, ensuring robust and durable end-products.
2. Cost-Effective Solution: As a cost-saving alternative to more expensive fillers, GCC helps reduce overall production costs while maintaining high-quality standards.
3. Optical Properties: It contributes to improved opacity and matte finish, partially replacing high-priced optical fillers like titanium dioxide, enhancing aesthetic appeal.
4. Environmental Compatibility: GCC is eco-friendly, non-toxic, and compliant with international environmental regulations, aligning with the sustainability goals of modern manufacturing.
5. Excellent Dispersion: Properly processed GCC dispersed uniformly within the plastic matrix minimizes interfacial defects, enhancing the overall material performance and reliability.
