Oxidized polyethylene wax is a polar wax made of polyethylene through oxidation process. Since the molecular chain contains polar functional groups such as hydroxyl and carboxyl groups, the compatibility with each component in the PVC melt is improved (relative to polyethylene wax and Fischer-Tropsch wax), the affinity with metal is also greatly improved, so the demolding effect or metal peeling effect of PVC melt is correspondingly improved. Generally divided into high density oxidized polyethylene wax and low density oxidized polyethylene wax.
In addition to being polar, high-density oxidized polyethylene wax is characterized by high viscosity and high melting point, which can significantly increase the viscosity of the melt. While improving the degree of plasticization of the melt, the metal peeling performance (release performance) is also corresponding. It is especially suitable for PVC rigid foam board, injection molding products, low calcium products and transparent sheets.
Low-density oxidized polyethylene wax has lower viscosity than high-density oxidized polyethylene wax, and the effect of promoting the improvement of plasticization degree is not obvious, but it has a significant effect on improving the extrusion speed and appearance gloss of PVC product processing, and is suitable for processing and application of most PVC products.
Oxidized Polyethylene wax application: Oxidized Polyethylene wax can be used for PVC film, profile, pipe, plastic processing. Oxidized Polyethylene wax can be used for the paper industry After emulsification, printing and dyeing and garment industry, water-based ink. Oxidized Polyethylene wax can be used for Wax products, Hot melt adhesive, adhesive etc.
