The following are the three SCG-Chem subsidiaries where ChEPS students have been interned:



  • Rayong Olefins Co., Ltd. is a subsidiary of SCG Chemicals and is a major producer of upstream petrochemicals mainly used as feedstock for Polyethylene (PE) and Polypropylene (PP) resins. Production was commenced in 1999. This upstream manufacturing has turned Siam Cement Group into one of the leading petrochemical players in Thailand and in Asia - Pacific.


  • Thai Polyethylene Co., Ltd., Thai Polyethylene (1993) Co., Ltd., Thai Polypropylene Co., Ltd. and Thai Polypropylene (1994) Co., Ltd., a Group of polyolefins manufacturers wholly owned by Cementhai Chemicals Co., Ltd., produce several categories of high quality polyethylene and polypropylene resins, raw materials widely used in plastic industry.


  • Siam Mitsui PTA Co., Ltd. was established upon cooperation of Cementhai Chemicals Co., Ltd. and Mitsui Chemicals, Inc. of Japan for producing Purified Terephthalic Acid (PTA) which is used as raw material supplying the pet bottle and polyester industry. Because the Company utilizes state-of-the-art and highly efficient technology of Mitsui Chemical Inc. of Japan as the production process of PTA. The process is widely accepted by most polyester producers in Asia as consitent and high quality products. Siam Mitsui PTA thus offers products of which quality complies with customers requirements, which can be consequently used to produce crystal clear PET bottles and non-flaw polyester fiber.


SCG-Chem is the sole sponsor of IR-ChEPS, in which a selected number of students work on an industrial research project for 12 months during their second year.  IR-ChEPS provides an added benefit to SCG-Chem because it allows more in-depth and complex research problems to be tackled due to much longer project duration.
