High-density oxidized polyethylene wax OA9 is a high-temperature lubricant for oxidative polymerization of polymers. It has a certain amount of carboxyl and hydroxyl groups in the molecule. It is a functional processing aid with excellent performance. OA9 is useful for the production of PVC foam boards, WPC, etc. Compared with ordinary oxidized polyethylene, PVC products have the following advantages:

　　Ø Increase plasticization while reducing torque;

　　Ø Can reduce the adhesive force of thermoplastic melting and increase the fluidity of the melt, improve demoulding, and increase output;

　　Ø Improve the gloss of the finished product and improve the appearance;
