Bayflex 963 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 963 system is used in the manufacture of microcellular polyurethane innersoles. The innersoles prepared from these compounds combine light weight, comfort, and durability. Processibility and dynamic flexural properties are excellent and have made the Bayflex 963 system a prime innersole material. As with any product, use of the Bayflex 963 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 963 system, listed below, are representative of typical performance characteristics of molded panels. Actual results may vary, depending on part design and processing conditions.
