| About |
|---|
| Baytec MS-051 is a modified diphenylmethane diisocyanate (MDI)-terminated polyester prepolymer used in the manufacture of high-property solid cast polyurethane elastomers. The excellent resilience and low compression-set properties have enabled this material to be used for low-durometer wheels, printing rolls, and squeegee blades. As with any product, use of Baytec MS-051 prepolymer in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.&& |
