Baytec MS-080 modified diphenylmethane diisocyanate (MDI)-terminated polyester prepolymer is used in the manufacture of high-property solid cast polyurethane elastomers. As with any product, use of Baytec MS-080 prepolymer in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
