RJ-7551 is a Si-C bond type of polysiloxane polyether copolymer. It used for the production of polyurethane rigid foam. RJ-7551 has been developed for 141B, water and hydrocarbons blown polyurethane foams, delivering very good foam stabilization and extremely fine celled foam. It may also be used as a general purpose surfactant for other rigid foam applications.
