Rokopol® iFlex S21 (polyetherpolyol)

Rokopol® iFlex S21 is a polyether copolymer polyol based on ethylene oxide (EO) and propylene oxide (PO), produced from glycerine.

It is supplied as a transparent liquid free of mechanical impurities, with the addition of BHT-free antioxidants. Thanks to its high purity and low emissions of volatile organic compounds (VOC), the product meets the most stringent quality and environmental protection requirements. It has a hydroxyl number in the range of 40–46 mg KOH/g and a dynamic viscosity of 1000–1300 mPas (25 °C). Rokopol® iFlex S21 ensures excellent process control and repeatability of production parameters. The product was developed as part of a research and development project co-financed by the European Union from the European Regional Development Fund.
