PETOL 28-3B is a tri-functional highly reactive polyether polyol, with a 6000 nominal molecular weight designed for obtaining high resilience flexible polyurethane foams. Due to the high content of EO, the product may become opalescent at temperatures below 30°C. PETOL 28-3B results from the addition of propylene oxide and ethylene oxide to glycerin, under base catalysis.
