High Thermal Stability Melamine Octamolybdate and Use Thereof as a Smoke Suppressant in Polymer Compositions
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.
POLYAMIDE COMPOSITIONS AND PLATING APPLICATIONS THEREOF
The present disclosure relates to polyamide compositions and resulting injection-molded articles that can be plated, e.g., metal coated, to form aesthetic injection-molded articles. The polyamide compositions may include from 45 wt. % to 75 wt. % of an polyamide, from 2 wt. % to 40 wt. % of an etchable filler, from 10 wt. % to 40 wt. % of a semi-structural mineral, and optionally from 0.1 wt. % to 13 wt. % of additive. The polyamide composition imparts very good surface appearance to injection-molded articles that are substantially free of visual defects.
