The current production augmentation will cater to surges in demand for automotive related polypropylene by Indonesia and neighboring countries and will reinforce the Company's presence in the ASEAN market.

The Mitsui Chemicals Group has targeted intensification and expansion of polypropylene production in seven major world markets (Japan, United States, Mexico, Europe, Thailand, China, and India). The production augmentation in the Thailand will reinforce the Company's already world top class production capability for automotive material use polypropylene.

Mitsui Chemicals and Prime Polymer will strategically intensify and expand operations through ongoing collaboration and reinforcement of production, sales, and technological support structures necessary in providing state-of-the-art, performance-driven materials to meet the needs of globally expanding automotive manufacturers.
