NINGBO INNO PHARMCHEM CO.,LTD. is a prominent supplier of chemical additives that are critical for enhancing plastic processing. Polyethylene Wax (PE Wax) is a key additive, particularly valued in plastic molding operations for its ability to optimize melt flow and significantly improve the surface quality of molded parts. This article delves into the beneficial applications of PE Wax in plastic molding.

Plastic molding, whether through injection molding, extrusion, or blow molding, involves transforming plastic resins into desired shapes under heat and pressure. The efficiency and quality of this process are heavily influenced by the rheological properties of the molten plastic. PE Wax, known for its excellent lubricating properties, plays a crucial role in these operations. It acts as both an internal and external lubricant, depending on the specific grade and application.

As an external lubricant, PE Wax reduces friction between the molten plastic and the metal surfaces of the mold or extruder die. This results in smoother flow, reduced shear stress, and easier release of the molded part from the mold. The benefit of PE wax for plastic molding as an external lubricant is particularly evident in rigid PVC processing, where it prevents sticking and ensures a clean surface finish. This also translates to reduced wear and tear on expensive molding equipment.

When used as an internal lubricant, PE Wax can modify the melt viscosity and improve the homogeneity of the plastic melt. This means the plastic flows more uniformly, leading to more consistent wall thickness in molded parts and a reduced likelihood of defects such as warping or sink marks. The ability of polyethylene wax to improve melt flow is a direct contributor to enhanced productivity and better part quality.

Furthermore, PE Wax contributes to the surface aesthetics of molded plastic products. It can enhance gloss, improve surface smoothness, and increase resistance to scratching and marring. For products where appearance is critical, such as automotive components or consumer electronics, the surface finish provided by PE Wax is a significant advantage. The objective of achieving optimal plastic molding surface quality is greatly aided by this versatile additive.
