Rokopol® FS3625 is a polyether polyol manufactured in the form of white non transparent 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 34.0 – 38.0 mg KOH/g with dynamic viscosity of 1300 – 1800 mPas at the temperature of 25°C.

Rokopol® FS3625 may be used for production of flexible polyurethane foams in the continuous (slabstock) or periodical (batch) manufacturing system. By means of the polyol and an appropriate selection of additives, (catalysts, silicones, foaming agents) hardened flexible slabstock foams with the rectangular section and the height up to 130 cm can be manufactured. Based on its excellent parameters the product may be widely used in the furniture industry for production of mattresses and furniture requiring increased foam hardness.

Most frequent applications of Rokopol® FS3625:

  • Possibility of producing foams with density from 16 to 80 kg/m3, hardness range of 3 – 10kPa and flexibility up to 35%;
  • The use of the product enables manufacturing foam with the breaking strength above 50 kPa and the relative tensile strength up to 50%;
  • Possibility of using the polyol with reactive polymeric polyols in order to reduce the foam hardness or to: increase or decrease the foam hardness;


Most frequent applications of Rokopol® FS3625:

  • Used for production of flexible foams with increased hardness
  • The polyol is used also in the construction industry, for production of mattresses and cushions;
  • The product is used for production of furniture requiring increased foam hardness

Products made based on Rokopol® FS3625 are of very high quality. Based on 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 flexible foams with very good density, flexibility and hardness parameters;
  • Compatibility with reactive polymeric polyols enables an extended application range;
  • Wide application range in the furniture industry;
