ADIPRENE DURACAST SE940 is an MDI-terminated polyether/polyester blend prepolymer having low free MDI content. A high performance 94A elastomer with excellent physical properties is obtained when this prepolymer is chain extended with DURACURE™ C3 or C3-LF. Other advantages are improved processing characteristics and easier management of health & safety during handling. The unique combination of properties exhibited by low free MDI prepolymers is superior to those available from TDI and conventional MDI prepolymers. DURACAST prepolymers cured with DURACURE C3 or C3-LF provide a superior hard segment and offer unique processing and productivity improvements. This high performance hard segment offers excellent physical and engineering properties, including high cut and tear resistance, improved flex fatigue, low temperature flexibility, excellent dynamics (at both low and high temperatures) and other high temperature properties. Traditionally, amine cures could not be used with MDI prepolymers due to high reactivity (short pot life) even though they offer some performance advantages such as high temperature resistance and tear properties. It also offers EH&S advantages as it is based on low free monomer technology and is a MBOCA free system. |
