Product Description
Bayflex MP-10,000 is a solid elastomer which has a flexural modulus of 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. As with any product, use of the Bayflex MP-10,000 system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.

Bayflex MP-10,000 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. Note: Component B should be agitated thoroughly prior to transfer of contents from the drum to the day tank.
