Bayflex XGT 2 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 2 gives equipment designers the flexibility to create large, complex parts that can be molded on existing injection machinery. The resin's soft feel and the ability to tailor part density through the addition of barium sulfate make this product ideal for applications that require some level of sound absorption, such as floor coverings in heavy trucks or equipment. In addition, the material is soft enough to be used for producing seals, gaskets and wire harness type applications. As with any product, use of the Bayflex XGT 2 system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability. |
