PVC

In the production of PVC, wax, along with fatty acids and esters, constitutes the lubrication system, which solves a series of problems caused by high melt viscosity. Due to its different compatibility with PVC resin, polyethylene wax is regarded as an external lubricant, directly acting between the material and the metal interface to prevent the formation of melt adhesion. Oxidized waxes and ester waxes with polar groups can significantly enhance the plasticization ability, provide excellent demolding performance and surface glossiness, and effectively ensure the production cycle.
