Plasticization Mechanism of Oxidized Wax

    During the molding and processing of polymer materials, there is friction between molten polymer molecules, known as internal friction. Internal friction increases the melt flow viscosity of the polymer, reduces its fluidity, and in severe cases, leads to overheating and aging of the material. To reduce friction between polymer molecules (i.e., reduce internal friction), one or more lubricants with certain compatibility with the polymer need to be added, which are called internal lubricants.

    As a new type of lubricant, oxidized wax has a structure and state in polymers similar to plasticizers. Oxidized polyethylene wax has good compatibility with polymers and can intercalate between PVC molecular chains like plasticizers, slightly weakening the mutual attraction between molecules, as shown in the figure below:

    Thus, during polymer deformation, molecular chains can slide and rotate relative to each other, thereby reducing internal friction between molecules, lowering melt viscosity, increasing fluidity, and facilitating plasticization.

    Qihong high-density oxidized polyethylene wax is in powder form. During batching, it can be uniformly dispersed into fillers to play an internal lubrication role. After sufficient high-temperature oxidation, it exhibits excellent thermal stability and aging resistance. Additionally, it imparts a good appearance to products without affecting their color and other properties.
