Characterization: Baydur STR/C-1000 is a moderate-viscosity, two-component, liquid structural RIM (reaction injection molding) system. Properties / Applications: Baydur STR/C-1000 is moderate-viscosity, two-component, liquid structural RIM (reaction injection molding) system. Component A is a modified polymeric diphenylmethane diisocyanate (PMDI) blend,and Component B is a totally formulated polyol blend. The Baydur STR/C-1000 system is used in the production of structural composite parts with long-fiber reinforcements. The reinforcement is placed in the mold, which is closed and then injected with the reactive resin. Baydur STR composites can be ten times stiffer than Baydur structural foams and have the excellent impact properties traditionally associated with Bayer polyurethanes. As with any product, use of the Baydur STR/C-1000 system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.
