Rokopol® RF551 is a general purpose polyether sorbitol polyol used for production of polyurethane (PUR) rigid and semi-rigid foam production in reaction with isocyanate. It mixes well with water. It exists in form of a clear, colourless to yellow liquid. It contains antioxidants (excluding BHT). It retains low viscosity (ca. 3000-5000 mPas) at relatively high functionality of f~4.5 and high hydroxyl value of 400-440 mgKOH/g.
