Bayflex MP-10,000 IMR is a solid elastomer which has a flexural modulus of approximately 10,000 psi (69 MPa) at room temperature. It is processed on reaction injection molding (RIM) equipment and is used for rollers, gaskets, and encapsulated windows. This system combines rapid demold times, excellent integrity at demold, improved release characteristics, and outstanding physical properties.

This system also offers the advantage of an internal mold release (IMR). It is formulated to provide excellent releasability during production of RIM encapsulated windows while still maintaining strong adhesion to primed glass. Compatibility between MP-10,000 IMR and current industrial in-mold coatings is equivalent to standard Bayflex MP systems. The incorporation of internal mold release technology into RIM modular window production reduces the frequency of external mold release application. This can increase productivity by decreasing cycle time and reducing the frequency of mold cleaning. As with any product, use of the Bayflex MP-10,000 IMR system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.
