Rokopol® is a general purpose multifunctional polyether sorbitol polyol for polyurethane (PUR) rigid and semi-rigid foam production in reaction with isocyanate. The product has a form of homogenous liquid in yellow to brown colour, containing BHT free antioxidants. It retains high viscosity of ca. 16 000 mPas with high functionality of f>5, and high hydroxyl value of ca. 470mgKOH/g.

Rokopol® RF475 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 slab foam spray application with low lambda value, as well as for foams of higher density. Physicochemical parameters of Rokopol® RF475 in formulation with other polyols, in particular those based on aromatic amines, enable obtaining PUR rigid foam with very good insulating properties, very good linear dimensional stability and resistance to low temperatures. The product has a wide application range, in particular in the construction industry.


Main application advantages of Rokopol® RF475:

  • The product ensures high crosslinking level of the foam;
  • Very good mechanical properties flame-retardant content;
  • Possibility of obtaining foam with very good insulating properties and very good linear dimensional stability;
  • Resistance to low temperatures;


Most frequent applications of PUR Rokopol® RF151:

  • Closed-cell foam for thermal insulation in cooling technology and for elevated temperatures;
  • PUR closed-cell foam for thermal insulation in the construction industry;
  • Used in spray thermal and acoustic insulation systems;
  • Used as a component for production of sandwich panels and insulation boards;
  • Used for insulation of pipelines, cables and wires;


Products made based on Rokopol® RF475 are of excellent quality. Based on the optimally developed manufacturing process this polyol is distinguished by very good parameters, not only in PUR systems.


Properties and applications:

  • Product dedicated for manufacturing PUR foam slab applications;
  • Very high quality of the end product based on the physicochemical properties of the polyol;
  • Applied in closed-cell foams used as insulation;
  • Used as a component for production of sandwich panels and insulation boards;
  • With very good mechanical and thermal insulation parameters;
