The Bayflex 110-50 system produces a solid urethane elastomer which has a flexural modulus of approximately 50,000 psi* at room temperature. This system can be used with or without milled glass fiber or mineral reinforcements. The Bayflex 110-50 system is used in applications requiring excellent impact properties such as automotive fascias, agricultural and construction equipment, specialty vehicles and recreational equipment.

The Bayflex 110-50 system is a formulated elastomeric reaction injection molding (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 110-50 system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.
