Business Overview
Highest-quality Polypropylene
GS Caltex began producing polypropylene (PP) in 1988. With steady facility expansion, we have secured capacity to produce 180,000 tons annually. Propylene (feedstock) is also produced in-house, leading to enhanced cost and quality competitiveness. Through ongoing R&D, we are working to develop and commercialize high performance materials. Our R&D efforts are contributing to industry-wide technological advancement.
New entry into the polyethylene market
GS Caltex produces 500,000 tons of high-density polyethylene (HDPE) annually by adopting CPChem's latest technology, the ADL process. GS Caltex's polyethylene has successfully entered new markets by maximizing synergy with the existing polypropylene business based on cost competitiveness through its own production of ethylene (feedstock), and is sold worldwide.
Mechanically Recycled PP compound (MR)
GS Caltex the only oil refinery in Korea who has been producing mechanically recycled(MR) PP compound resins from 2010, in order to achieve Net Zero. From 2022, we have signed agreements with pre-treatment partners of each source (Automotive/Home Appliances/Household) and secured high quality MR sources. With such effort, we secure stable supply chain of MR sources and produce MR compound which have comparable quality of virgin PP.

PP Compound Business Going Global
In 2008, GS Caltex started its first overseas PP compound plant in Langfang, China (capacity: 51,000 TPA), followed by GS Caltex (Suzhou) Plastics (58,000 TPA) in 2010. In 2011, we became the first Korea-based PP compound to enter the European market by establishing GS Caltex Czech, s.r.o. (60,000 TPA) in 2011. GS Caltex again made strides in 2016 by establishing a plant in Mexico (20,000 TPA). Our extensive global network enables us to supply materials to many global manufacturers including Samsung, LG, Hyundai, and Honda.

PP Compound
High performance resin with reinforced properties
PP (polypropylene) compounds are made by adding functional additives to PP (homo, random, or impact), aimed at enhancing certain mechanical performance compared to neat PP. GS Caltex’s PP compound is categorized into many different grades according to their purpose (high stiffness, electro-conductivity, heat resistance, etc). PP compounds are primarily used for automobile and home appliance components.
