Описание материалов:
Bayflex XGT-15 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-15 system has a flexural modulus of 16,00 psi at room temperature. It is used in applications requiring long shot times allowing large parts to be made on smaller equipment. The Bayflex XGT-15 system is suitable for use in glass encapsulation applications, or in applications requiring excellent impact properties, such as bus and truck bumpers or equipment housings. As with any product, use of the Bayflex XGT-15 system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.
