Exhibits strong nucleation, high processing latitude, high stabilizin potency and froth supporting effect. Possesses combination of high activity with medium flame retardant (FR) properties. Offers emulsification of the raw materials (polyol/TDI/MDI/water), high nucleation of gas bubbles, low to medium density, delayed & controlled cell opening and reduced defects caused by shear forces. Provides porosity, load-bearing properties and elasticity. Suitable for producing foams with FR requirements like Cal 117 and MVSS 302. Used in CO2 foams and foams with optimized fine cell structure. TEGOSTAB® B 8255 by Evonik is recommended for low VOC conventional foams.
