Olefins

Playing a central role in the development of the domestic petrochemical industry
through stable supply of high-quality products

“ SK global chemical started operating Korea’s first naphtha cracking center (NCC) in 1972,
and we are now producing approximately 860,000 tons of ethylene annually.
We are reliably supplying ethylene/propylene/butadiene, the core raw materials for petrochemical products,
to our Ulsan CLX, other domestic petrochemical plants, and various overseas customers. ”

The olefin business belongs to the upstream in the petrochemical chain. By producing raw materials of synthetic resins,
the olefin business adds value to our products and contributes to our stable profit generation.
In addition, based on our operational excellency accumulated over the last 40 years,
we are maximizing the efficiency of our manufacturing processes.

In addition, based on the integration throughout the petrochemical industry from petroleum to polymer,
SK global chemical is creating synergy across the business.
Moreover, we aim for a sustainable growth based on our competitiveness in plant operation and global joint projects
such as Sinopec-SK(Wuhan) Petrochemical.
