In addition, the company is producing PP's raw material, propylene, through its own Propane Dehydrogenation (DH) Process. Polypropylene resin produced and supplied by Hyosung, TOPILENE is a high-yield positional polypropylene merging the company's polymer synthesis technology accumulated in the chemical textile industry, HYPOL Process of Japan's MITSUI Petrochemical Co., Ltd., which possesses the world's most advanced processes, the advanced UNIPOL Process technology and various catalyst application technologies of the U.S. DOW. In particular, Hyosung's TOPILENE resin is supplying excellent products that meet customer needs and is leading the differentiated product market. It is well-known and widely used in Southeast Asia, the Middle East and Europe as well as in Korea while the company is making great efforts to realize Customer Satisfaction Management through product development and customer services.

Furthermore, as we built up a vertical system from raw materials to final products by operating a propylene manufacturing plant using an up-to-date Propane Dehydrogenation (DH) process, we have been able to secure a stable supply base for the main raw material of polypropylene resin, propylene of high purity, as well as the technology required.
