VIBRATHANE B844 is a medium performance, polyether-based TDI-terminated liquid urethane prepolymer that is readily processable by conventional hand and machine mixing techniques. When cured with 4'4- Methylene-Bis [2-Chloroaniline], this member of the VIBRATHANE family produces vulcanizes with an 80 Shore A hardness. These elastomers have properties similar to, but somewhat lower than those of VIBRATHANE B 602. They are most often used in less demanding applications. The polymer us characterized by good processibility due to its:
