Rokopol® MS5225 is a polyether polyol in the form of white, opaque liquid. The product contains BHT free antioxidants and is marked by high purity and low emission. The product hydroxyl value is in the range of 25.0 – 29.0 mg KOH/g with dynamic viscosity of 2000 – 2600 mPas at the temperature of 25°C.

Rokopol® MS5225 may be used for production of highly flexible polyurethane foams in the continuous (slabstock) or periodical (batch) manufacturing systems, as well as for foam moulding production. By means of this polyol and an appropriate selection of additives, (catalysts, silicones, foaming agents), highly flexible slabstock foam with the rectangular section and the height up to 100 cm can be produced. Based on its excellent parameters the product may be widely used in the furniture and automotive industries.

Main application advantages of Rokopol® MS5225:

  • Possibility of producing foams with density from 25 to 80 kg/m3, hardness range of 2 – 7kPa, and flexibility up to 55%;
  • The use of the product enables manufacturing foam with the breaking strength above 50 kPa and the relative tensile strength above 60%;
  • Possibility of using the polyol with reactive polymeric polyols in order to: eliminate the cold-flow effect, increase the slab height, modify the foam hardness, as well as to optimize the foam cell openness;


Most frequent applications of Rokopol® MS5225:

  • Used for production of flexible foams of increased quality
  • The polyol is used in the furniture industry for production mattresses and cushions;
  • The product is used in the automotive industry for production of car seats;

Products made based on Rokopol® FS3625: are of very high quality. Thanks to the optimally developed manufacturing process this polyol is distinguished by very good parameters and a wide range of possible applications.


Properties and applications:

  • High purity and low emission;
  • Possibility of obtaining highly flexible foams with very good density, flexibility, breaking strength, and comfort ratio parameters;
  • Compatibility with reactive polymeric polyols enables an extended application range;
  • Wide application range in the furniture industry;
  • Product used also in the automotive industry;
