According to chemical industry sources on Sunday, Hyosung recently signed a memorandum of understanding (MoU) with Iran's state-run National Petrochemical Company in the business of polypropylene (PP), thermoplastic polymer used in making plastic products and home appliance, products. The Korean company said it has been in talks with its Iranian counterpart to determine the feasibility of its PP business in the country, but has not made any conclusion yet. Industry experts expect Hyosung looking to expand its offshore manufacturing network would set up a PP production base in Iran. The company has inked an agreement with Vietnamese government to build a PP plant at a cost of $336 million in February last year."
