Since the production of Changling Refining and Chemical Polypropylene Plant, it has mainly produced general materials such as PPH-T03 and FO3G special materials, which have been recognized by users in the central and eastern markets of China for their good product quality and processability.

Developing high-end and diversified brand polypropylene products has become the main topic for polypropylene technicians in Changling Refining and Chemical Company.
