The addition of microcrystalline wax can significantly improve the flowability of polyolefin plastics. During processing, good flowability helps the plastic fill the mold more effectively, thereby reducing defects in the finished products—such as bubbles and sink marks—and improving product quality. In addition, microcrystalline wax effectively improves the dispersion of fillers and additives. By enhancing compatibility among the various components, it makes the plastic material more uniform and consistent. This not only helps improve the physical properties of the finished products—such as strength and toughness—but also enhances their appearance, resulting in a smoother and finer surface finish.
