The PTA plant uses paraxylene (PX) produced within GC Group as the primary feedstock. The PET plant relies on two main feedstocks, namely PTA obtained from PTA plants in GC Group and MEG obtained from MEG plants in GC Group. The PS plant uses styrene monomer (SM) as the primary feedstock, obtained both through purchase agreements with domestic producers and through imports from various regions to ensure supply stability and competitiveness. The rotomolding compound plants use LLDPE as the primary feedstock which partially procured from external sources The PP compounding plant obtains PP partially from PP plants in GC Group.
