Product Description:
WynPUF® XH-1685 foam stabilizer is a Si-C bond type of polysiloxane polyether copolymer. It has been originally developed for HCFC, water and hydrocarbons blown polyurethane foams, delivering very good foam stabilization and extremely fine celled foam; however industrial experience has demonstrated that it may also be used as a general purpose surfactant for other rigid foam applications.
