Bayflex 954 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 954 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 954 system a prime soling material for fashion and casual shoes. As with any product, use of the Bayflex 954 system in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability. The properties of the Bayflex 954 system, listed below, are representative of typical performance characteristics of molded panels. Actual results may vary, depending on part design and processing conditions. |
