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.
