PE filler masterbatch is often used to reduce the cost of raw materials. By incorporating fillers like calcium carbonate or talc, manufacturers can lower the overall resin content in the formulation, reducing material costs.

The addition of fillers can enhance the stiffness and rigidity of the molded parts. This is particularly useful when producing large, hollow, or structural components that require added strength and dimensional stability.

The specific benefits and applications of PE filler masterbatch in rotational molding can vary depending on the type and concentration of fillers, the design of the mold, and the intended use of the final product.
