Baytec MS-242 is a modified diphenylmethane diisocyanate (MDI)-terminated polyester prepolymer. It is used in the manufacture of high-property solid cast polyurethane elastomers, such as forklift tires, sheet goods, wheels, rollers, and seals. As with any product, use of Baytec MS-242 prepolymer in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.
