Bayflex XGT-50 Black is a black-pigmented elastomeric polyurethane system used in the reaction injection molding (RIM) process. The formulated system is supplied as two liquid components: Component A is a diphenylmethane diisocyanate (MDI) prepolymer ,and Component B is a polyether polyol system. Note: The polyol component phase separates upon standing and must be thoroughly mixed via mechanical means prior to use. Bayflex XGT-50 Black system has a flexural modulus of 50,000 psi* at room temperature. It is used in applications requiring excellent impact properties, such as bumpers for buses and other vehicles. As with any product, use of Bayflex XGT-50 Black system in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability. |
