Bayflex XGT-140 is an elastomeric polyurethane system used in the reaction injection molding (RIM) process. The system is supplied as two liquid components: Component A is a modified diphenylmethane diisocyanate (MDI), and Component B is a polyether polyol system.
The extended gel time of Bayflex XGT-140 system gives equipment designers the flexibility to create large, complex parts that can be molded on existing injection machinery. The resin 's excellent surface quality and high impact resistance make it a candidate for agricultural equipment, heavy-duty trucks, specialty transportation, and marine applications. As with any product, use of the Bayflex XGT-140 system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability. (更多..) |
