R & DB Labs - Hyosung will develop the world's best technology to enrich our everyday lives.

The cradle of cutting edge technology that lead the global market

Established as Korea’s first R&D Center affiliated with a corporation in 1971, Hyosung R&DB Labs has expanded its research scope to raw materials and products of chemical, and new materials based on R&D capacities in synthetic fiber research, the driving force behind Korea’s industrialization.
Hyosung’s ‘Central laboratory’ and ‘Production Technology Center’ have been integrated to ‘Hyosung R&DB Labs’ for a greater synergy in September 2006. Hyosung reorganized its structure into five major research groups based on 10 core basic technologies, in order to create new business opportunities in 2011.
In addition to research technologies for future business areas, which are going to provide the basis for future growth, Hyosung R&DB Labs are developing new products and processes and help them widely utilized as rapidly as possible.
