DONGSUNG CHEMICAL CO., LTD.

Since its founding in 1959, Dongsung Chemical has been leading the polyurethane field,

developing and producing essential materials for everyday life―from footwear to automotive,

electrical & electronics, and building & construction. Our polyurethane resins are trusted by

world-class sports brands, while our advanced polyurethane materials are applied in automotive

interiors and components.

Today, we are redefining our brand identity from a chemical company to a science company.

Together with our affiliates ―Dongsung Finetec, an energy solutions company, and Genewel, a

life sciences company―we are securing future growth through four strategic pillars: eco-friendly,

high-performance, energy, and bio-health.

As a compostable packaging solution from Dongsung Chemical, ECOVIVA® is designed to

compost into water and carbon dioxide under certified conditions, without leaving microplastic

residues. When appropriately collected and processed, it contributes to CO2 reduction across

the entire lifecycle from production to disposal.

ECOVIVA® achieves physical properties comparable to petroleum-based plastic packaging,

offering a sustainable choice that helps protect the planet while maintaining consumer

convenience.
