Bayflex 120-50 is a polyurea RIM system designed to provide increased productivity compared to the typical amine-extended urethane systems. Bayflex 120-50 polyurea is recommended for applications such as automotive fascia, side moldings, exterior trim panels, wheel well flares, etc. Faster cure time, less frequent application of external mold release agent, and reduced mold cleaning are possible, providing increased productivity. (A 40% increase in parts per shift has been observed in test applications.) The Bayflex 120-50 polyurea system also provides a superior property profile compared to amine-extended urethane systems, with better dimensional stability and part appearance. Reinforcements, such as milled glass fibers, wollastonite, and Covestro's proprietary DOI filler can be used for further improvement in overall dimensional stability. As with any product, use of the Bayflex 120-50 polyurea system in a given application must be tested (including field testing, etc.) in advance bythe user to determine suitability. Bayflex 120-50 is a formulated reaction injection molding system (RIM) supplied as two liquid components. Component A is a diphenylmethane diisocyanate (MDI) prepolymer and Component B is a polyether amine. |
