Specialty polyol for use in cast polyether-based polyurethane (PU) formulations
NORYL™ AP2001G polyol is a low molecular weight di-functional polyol based on polyphenylene ether (PPE). The incorporation of NORYL AP2001G polyol into a solid elastomer matrix can demonstrate structure-property benefits in traditional cast polyurethane material formulations.
SABIC’s NORYL™ AP2001G polyol can help to support formulators of cast polyurethanes (PU) in developing products that require improved toughness and modulus while maintaining or improving elongation. The specialty polyol can partially replace PPG (polyether glycol) and/or PTMG (polytetramethylene ether) glycol) in cast PU formulations. Potential benefits include enhanced hydrolytic and chemical resistance, improved heat resistance and thermo-oxidative stability, increased abrasion and tear resistance and electric insulation properties.
Potential Applications:
Hot cast elastomer solutions may benefit applications that require more durability and better performance at high temperatures and under hydrolytic conditions. Potential applications include print rollers, protective coatings on pipes for slurry pumping applications, PU wheels, seals and gaskets, tires and mining screens. SABIC’s new NORYL™ AP2001G aromatic polyol can help to enhance hardness and toughness performance of MDI-BDO cast polyurethanes at high temperatures up to 70°C, which potentially allows MDI-BDO cast PU to be used in extreme conditions, such as for oil and gas exploration, gasketing and mining applications.
