BayGranite™ is an inorganic hydrated alumina designed for use in polymer systems as a flame retardant and smoke supressive additive. BayGranite® 17 is more accurately designated chemically as aluminum trihydroxide, Al(OH)3, and is produced through processing of alumina-bearing feedstocks. Although BayGranite® 17 is a dry powder, when heated above approximately 220°C it decomposes into approximately 35% water and 65% alumina by weight. BayGranite®17 is a nonabrasive, low density material with a Mohs hardness index of 2.5 - 3.5 and a specific gravity of 2.42. Almatis BayGranite®17 ATH is compatible with polymer systems, and is designed for applications that require low-soda ATH products.

FlameGard™ is a ground Bayer hydrated alumina designed for specific application in polymeric adhesive backing of tufted carpeting to provide a level of flame retardancy to the carpet system. It is specially ground to maintain relatively coarse particle distributions in the median range of 22 to 26 microns and provides a high loading potential in high viscosity backing compounds. FlameGard ATH has a slight off-white or ivory color that is acceptable in most applications.
