About SKC

SKC, a chemical and advanced-materials affiliate of SK Group, has reshaped itself from a polyester-film producer into a supplier of inputs for batteries and semiconductors. Its copper-foil unit SK Nexilis makes the ultra-thin conductive foil wound into lithium-ion cells, while subsidiary Absolics is developing glass substrates for advanced chip packaging. A legacy chemicals operation centered on propylene oxide and related derivatives continues to generate cash. The company sells to battery cell producers, chipmakers, and industrial customers, with earnings driven by volume growth in the newer materials lines and product spreads in chemicals.

Investors approach SKC as a portfolio-transition story, weighing capital spending on battery and semiconductor materials against the cash generation of its mature chemical business. Copper-foil profitability depends on electric-vehicle cell demand and on pricing power against Asian competitors, making the shares sensitive to the battery cycle. The Absolics glass-substrate venture ties part of the valuation to adoption timelines at large chip customers. As an SK Group affiliate, the company's funding decisions and asset sales are also read in the context of group-wide restructuring priorities.

SKC was established in 1976 within the Sunkyong group, the forerunner of today's SK, and a year later produced South Korea's first polyester film, a base for the videotapes and packaging materials that defined its early decades. It later became Korea's pioneer in propylene oxide production, building the chemical arm that still underpins the company. The decisive break with its past came in 2020, when it acquired copper-foil maker KCFT and renamed it SK Nexilis, followed by the 2022 sale of the legacy film business and the founding of U.S.-based substrate venture Absolics. SK Inc. is the controlling shareholder.

Each SKC business earns money differently. Copper foil is sold to battery cell makers under volume agreements where thinness, tensile strength, and consistent quality command premiums, and where plants must run near capacity to cover heavy fixed costs. The chemical unit earns spreads between propylene feedstock and the prices of propylene oxide and downstream glycols, margins that move with regional supply balances. Absolics aims to sell glass substrates that replace organic materials in advanced chip packages, a product still moving from qualification toward commercial volume as of 2024. Competitively, SKC faces entrenched Asian foil rivals and global chemical majors simultaneously.
