GS CALTEX BUSINESS — CHAPTER 04
980,000 tons a year, from HIPRENE in 1988 to MFC —
the fourth chapter: gas becomes material.
The double bonds olefins left behind now join hands. One alone is a gas — tens of thousands, linked, become a material.
ORIGIN
From the Greek poly (many) and meros (parts) — a polymer is literally something made of many pieces. The Korean term, 중합체, says the same: matter joined again and again.
A single ethylene is just a gas molecule. Link tens of thousands into a chain, and it becomes something else entirely — film, containers, car parts. Chemistry where pieces add up to properties.
01 — MONOMER
Ethylene and propylene are the leading monomers that make up polymers. Ethylene becomes the main feedstock for polyethylene (PE), and propylene for polypropylene (PP).
01 — POLYMERIZATION
A monomer, repeatedly bonded to itself with the help of a catalyst, forms a long-chain macromolecule — this process is called polymerization. By adjusting the catalyst and process conditions, we can achieve the specific strength, flexibility, clarity and other properties a given use requires.
01 — PELLET
The polymer produced through polymerization is formed into small pellets for easy handling and transport. These pellets are then molded and processed into packaging, containers, pipes, automotive parts, appliances and countless other products.
POLYMER 980K TONS / YR02 — CAPACITY
Polyethylene (PE) is a leading synthetic resin made by polymerizing ethylene. GS Caltex applies CPChem's Advanced Dual Loop (ADL) process to produce 500,000 tons a year of high-density polyethylene (HDPE), used across everyday goods, packaging, pipes, and construction and industrial materials.
Compound resin is made by blending rubber, fillers and additives into PP and other synthetic resins to engineer the properties a specific use requires. Its range of stiffness, impact resistance and heat resistance makes it suitable for automotive interior and exterior parts, appliance components and more.
Polypropylene (PP) is a leading synthetic resin made by polymerizing propylene. GS Caltex has produced polypropylene since 1988 and today has a capacity of 180,000 tons a year, with products engineered for a wide range of uses and properties — from food containers, film and fiber to automotive and appliance materials.
03 — TECHNOLOGY
Drawing on R&D capabilities built up over decades in the polymer business, GS Caltex develops high-performance materials engineered for diverse uses and customer needs.
LFT (Long Fiber Reinforced Thermoplastics) is a composite material reinforced with long fibers to enhance a thermoplastic resin's mechanical and thermal properties. Its strength and light weight make it a metal-replacement material used in automotive parts and other applications.
A compound resin produced using mechanically recycled feedstock from waste plastic. GS Caltex has produced low-carbon MR compound resin since 2010 and continues to develop and expand supply of high-quality recycled materials made from end-of-life automotive, appliance and household plastics. In 2025, it became the first in Asia to earn RecyClass certification across the entire value chain for end-of-life vehicle plastic materials.
04 — HISTORY
05 — GLOBAL
GS Caltex has strengthened the global competitiveness of its compound resin business by establishing overseas production subsidiaries in China and Czechia, building on its domestic production base and R&D capabilities. We continue to expand local production and supply capacity to meet the demand of global automotive, appliance and other customers.

The feedstocks born in refining also lead on to high-quality base oil. The next chapter follows the base oil business, which uses unconverted oil from the refinery's upgrading process to produce the foundational feedstock of premium lubricants.
