  • High thermal stability melamine octamolybdate and use thereof as a smoke suppressant in polymer compositions
    Patent number: 11142630
    Abstract: Processes for producing melamine octamolybdates having high thermal stability include a step of reacting molybdenum trioxide and melamine in an acidic aqueous system at a pH of less than or equal to about 4 to form a slurry of the melamine octamolybdate. The resulting melamine octamolybdate can be characterized by a decomposition onset temperature (or a temperature at a weight loss of 1%, or a temperature at a weight loss of 2%) on a thermogravimetric analysis curve of greater than 300° C., and is useful in polymer compositions as a smoke suppressant.
    Type: Grant
    Filed: September 23, 2019
    Date of Patent: October 12, 2021
    Assignee: J.M. Huber Corporation
    Inventors: Yue Liu, Aleksey Isarov, David Dwayne Temples, David Stanley Reece, Mitchell Lee Pierce
