Cost Reduction: Calcium carbonate is less expensive than polyethylene resin. Incorporating calcium carbonate into PE formulations can significantly reduce material costs, making the composite material more economical for various applications.

Improved Stiffness and Rigidity: Calcium carbonate acts as a filler and reinforcing agent in PE, increasing the stiffness and rigidity of the composite material. This enhanced stiffness is beneficial for applications requiring structural integrity and dimensional stability.

Reduced Density: Calcium carbonate has a lower density than PE resin. By adding calcium carbonate to PE formulations, the density of the composite material can be reduced while maintaining volume. This can lead to weight reduction in the final product, which is advantageous in applications where lightweight materials are desired.
