Eco-friendly technology research that stays one step ahead of customer needs
The SAMBU Fine Chemical
R&D Center
Since its opening, the center has worked tirelessly to develop the best products for our customers' needs and to become a Market Leader by always introducing cutting-edge new products one step ahead.
Our Driving Force for Growth
Founded in 1983 as a supplier of release agents and cleaners for footwear manufacturing, SAMBU Fine Chemical introduced the world's first water-based release agents and cleaners. Since then we have expanded into TPU, into fabrics made with TPU, and now into PU foam, and our evolution continues.
SAMBU's growth has been driven by a core management value: understand and analyze our customers' needs first, then supply products that meet them. At its heart have been our unstinting investment in technology and the continuous research of our R&D Center.
The Keyword “Eco-friendly”
“Eco-friendly” is the keyword that best represents SAMBU Fine Chemical. We strive to be a foundation on which workers, users and local communities can thrive together.
To develop innovative eco-friendly products and create new eco-friendly business areas, the R&D Center has carried out extensive research and development in eco-friendly chemical products, water-based polyurethane resins, recycled polyurethane sheets and more.
ISO Certification
In 2014, we obtained certification for our quality, environmental and occupational health and safety management systems.
