Bayflex® XGT-16 CLEAR Datasheet,PUR-Ether/MDI,Covestro

Message
Bayflex XGT-16 Clear is an 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. Bayflex XGT-16 Clear system has a flexural modulus of 16,00 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 the Bayflex XGT-16 Clear system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.
