Rokopol® RF151 is a propoxylated Mannich base, reactive multifunctional polyether polyol for rigid and semi-rigid polyurethane (PUR) foam production in reaction with isocyanates. The product has a form of antioxidant free liquid in orange to brown colour. It retains high viscosity of ca. 22 000 mPas at 25°C with high functionality of f~5, and high hydroxyl value of ~450mgKOH/g.

Rokopol® RF151 is a product dedicated for manufacturing polyurethane (PUR) products of higher viscosity, high flame-retardant content, and very good mechanical properties of rigid foam. The product is in particular recommended for PUR rigid foam spray application with low lambda value, relatively low density, and good adhesion to polyurethane foam and other substrates, including metal and wood. Mannich polyols are very well miscible with typical polyols for rigid foam application, i.e. sorbitol and sugar based polyols, and most of polyester polyols. It ensures comfortable easiness in developing new rigid foam polyester systems. The product has a wide application range, in particular in the construction industry.  


Main application advantages of Rokopol® RF151:

  • Possibility of catalysis reduction, which is of particular importance while using new physical foaming agents that have detrimental effect on catalytic systems;
  • Improved mechanical parameters of the rigid foam core,
  • Aromatic chemical composition ensuring improved flammability properties of rigid foam;
  • Homogenous and fine cell structure of rigid PUR foam;


Most frequent applications of PUR Rokopol® RF151:

  • SPF spray foam;
  • Closed-cell PUR foam for heat insulating;
  • Slabstock PUR sandwich panel production systems;
  • Rigid foams
  • Used for thermal and acoustic spray insulation systems;
  • Used as a component for production of sandwich panels and insulation boards;



Products made based on Rokopol® RF151 are of excellent quality. Based on the optimally developed manufacturing process this polyol is distinguished by very good parameters, not only in PUR systems.
