IRPC is a  producer  of  upstream  petrochemical  products, namely olefins and aromatics. These upstream products are feedstocks for  IRPC’s  downstream  petrochemical plants: 931 KTA of polyolefins (HDPE and PP, UHMW-PE) and 383 KTA of styrenics (ABS, SAN, PS, and EPS). These downstream products are sold to producers of finished  plastic  products  in  Thailand and overseas under the brand POLIMAXX.

Focusing on the growth of its petrochemical business, IRPC endeavors to stay abreast of global environmental and technological changes through researching and developing new products that will increase its competitiveness. Recent innovations include paralene from natural ingredients, recycled compound resin, and acetylene black for Li-ion batteries (Pim-L and Pim-AL).

Furthermore, through the Eco Solution project, IRPC has pioneered a closed loop production for the plastics industry in which one plant’s waste is efficiently used as another’s feedstock. The model ensures that no waste would get out of the loop and become a burden to society
