Concentrol is a innovative producer of custom silicone surfactants for a wide range of polyurethane foams, under the brand name STB-PU. The family-owned company was founded in 1941, with over 80 years of experience in the chemical sector.
STB-PU surfactants are designed to improve emulsification of the PU foam raw materials, offering sufficient nucleation and structural stabilization during the expansion process. In turn, this helps to control the size and distribution of the foam’s cells.
