HMC Polymers is Thailand’s pioneer producer of PP. We founded our first plant at Map Ta Phut Industrial Estate in Rayong in 1983, which has since been systematically managed to facilitate relentless expansion while maintaining operational excellence along with operating efficiency.

We produce over 810,000 tons of PP a year from 3 production lines with Spheripol and Spherizone technologies – the latest technology from LyondellBasell, the world’s chemical leader and our joint-venture partner. We also operate a propane dehydrogenation (PDH) plant, located next to the PP plant, to ensure long-term feedstock supply.

In 2022, when construction of the 4th production line, equipped with the Spherizone technology, is completed, our PP production capacity will surge beyond 1,000,000 tons per year. This will secure our position as the largest and most sophisticated integrated PP producer in Southeast Asia, certified with ISO 9001 and ISO 14001 standards.

Our PP products are marketed under the ‘Moplen’ brand, which covers Homopolymer, Heterophasic Copolymer, and Random Copolymer grades as well as PP of specialty grades, including Adstif, Clyrell, Adsyl, Purell, and Hostalen PP.


HMC Polymers provides integrated logistical services for exports to various overseas destinations in Asia and around the world. Our services facilitate product shipment from Laem Chabang Port in Chon Buri, a world-class commercial port located near our plants that also handles deepsea vessels.

We arrange for storage and delivery of PP using modern methods while offering various types of packaging, including the 25-kg bag (with or without pallets) and the jumbo bag, for loading onto land freight containers or large trucks as well as onto sea freight containers.

Health, Safety, and Environment

HMC Polymers recognises the need for responsibility to all stakeholders with primary regard for impact on health, safety, and environment. We also believe that development and improvement of the quality of lives of people in surrounding communities and Thai society at large is a mission borne by our business operations. We therefore initiated several projects where our own products - PP – can bring social benefit.
