LYB is a leading global producer of ethylene oxide and propylene oxide, essential building blocks in a wide range of industrial and consumer applications. Our world-scale facilities produce propylene oxide alongside co-products such as styrene monomer (SM) and tertiary butanol (TBA)—ensuring efficient, large-scale production and supply reliability.

We are also a major producer and marketer of ether components for clean-burning automotive fuels. Our fuel ethers, including MTBE and ETBE, deliver:

• High octane and excellent combustion characteristics
• Improved fuel performance and lower emissions of ozone and particulate matter

In addition, LYB manufactures tetrahydrofuran (THF)—a key raw material used in the production of spandex fibers and PVC pipe cements—as well as diethyl ether for pharmaceutical and industrial applications.

From fuels to fibers, LYB epoxides and ethers are essential to enabling modern mobility, materials and manufacturing.
