Covestro Bayflex® 110-35 IMR Urethane Elastomer
Categories: Polymer; Thermoset; Polyurethane, TS

Material Notes: Characterization: Bayflex 110-35 IMR system produces a solid urethane elastomer which has a flexural modulus of approximately 33,500 psi* at room temperature.

Properties / Applications: Bayflex 110-35 IMR system produces a solid urethane elastomer which has a flexural modulus of approximately 33,500 psi* at room temperature. This system is used to provide multiple releases of large reaction injection molding (RIM) parts, such as automotive fascias. The system contains internal mold release (IMR) and is used with milled glass fiber or mineral reinforcements. Bayflex 110-35 IMR is a formulated RIM system supplied as two liquid components. Component A is a diphenylmethane diisocyanate (MDI) prepolymer, and Component B is a polyether polyol system. As with any product, use of the Bayflex 110-35 IMR system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.
