Описание материалов:
Bayflex 906 is a fully compounded, water-blown, polyether-based polyurethane system consisting of two liquid components. Component A is a modified diphenylmethane diisocyanate (MDI) prepolymer, and Component B is a polyether polyol system. Bayflex 906 system was developed for use in a wide variety of applications requiring a microcellular core and a tough, abrasion-resistant outer surface. Examples of possible applications include appliance handles, office chair armrests, and dunnage strips. As with any product, use of the Bayflex 906 system in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
