Oxidized polyethylene waxis made from polyethylene wax after special oxidation process. The molecular chain has certain functional groups, so its miscibility with polar resin has been significantly improved. Due to a certain amount of carbonyl and hydroxyl groups in the molecular chain of oxidized polyethylene wax, the compatibility with fillers, pigments and polar resins is significantly improved. The wettability and dispersibility in polar system are better than that of polyethylene wax, and it also has coupling property. Due to its high melting point and low viscosity, it promotes good resin fluidity, relatively reduces the power consumption of resin mixing, reduces the adhesion between resin and mold, is easy to remove film, plays the role of internal and external lubrication, and has good antistatic property.
At present, oxidized polyethylene wax is widely used in PVC foam board, but it is less used in other aspects due to price reasons. PVC foam board is the most difficult to produce in PVC products, which has the most problems and is the most difficult to solve. The plasticization can be significantly accelerated after adding oxidized polyethylene wax. Here we can see the uniqueness of oxidized polyethylene wax.
