PolyU L 8000 is a specialized high-molecular weight polyether polyol (PPG), produced by ring-opening polymerization using a double metal cyanide (DMC) catalyst. PolyU L 8000 can be used for production of silane-modified polymers.

PolyU L 8000 is a homogeneous, clear liquid. PolyU L 8000 has a dynamic viscosity at 25°C in the range of 2600–3600 mPas, a functionality of hydroxy groups close to f ~2 and a hydroxy value in the narrow range of 13-15 mg KOH/g. PolyU L 8000 shows a low degree of unsaturation, low volatile organic compounds (VOC) content, low metal ion content and contains BHT-free antioxidants.
