          Polymer polyols POP H-45 which are based on  high  active  flexible  foam polyether polyols are synthesized by free radical graft polymerization with initiator and monomers of styrene and acrylonitrile under specific temperature and nitrogen protection. Currently they represent one of the most important groups of polyols for molded, flexible slabstock and semi-rigid polyurethane foams. They are BHT-free and amines-free high reactivity polymer polyols characterized by low viscosity, low monomer residues and high solid content at 41%~45%. The products are used to manufacture flexible and semi-rigid polyurethane foams of high load or highmodulus.
