Polymer polyols CHP-2150 which are based on general polyether polyols are synthesized by free radical graft polymerization with initiator and monomers of styrene and acrylonitrile under specific temperature and nitrogen protection. They are characterized by BHT free,low monomer residues,low viscosity and high solid content at 48%~52%. They gives a good flowabitily when mixing with water. The foam made by the products has low density gradient and uniform and fine cell structure. The products are mainly used in the ultra–high hardness flexible slabstock foams and flame lamination foams.

Polymer polyols CHP-H30 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. At present they are important species of polyols applied in molded, flexible slabstock and semi-rigid polyurethane foams. They are BHT-free and amine-free high reactivity polymer polyols with low monomer residues, which are used for the high resilience slabstock foams, molded resilience foams,integral skin foams and semi-rigid polyurethane foams, etc.
