Bayflex 952 is a fully compounded polyether-based polyurethane system consisting of two liquid components which can be water-blown. Component A is a modified diphenylmethane diisocyanate (MDI) prepolymer, and Component B is a polyether polyol system. The Bayflex 952 system is used in the manufacture of microcellular polyurethane shoe soles. Soles prepared from these components combine light weight, comfort, and durability. Processibility and dynamic flexural properties are excellent over a wide range of densities. The combination of excellent physical properties and ease of processing has made the Bayflex 952 system a prime soling material for single-density soles for fashion and casual shoes. As with any product, use of the Bayflex 952 system in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability. |
