Color -All ALCOA White Hydrates offer whiteness.
Purity-The process unique to Alcoa results in an organic-free ATH.
Flame Retardancy-Alumina Trihydrate, a dry-white powder, contains 34.5% by weight chemically-bonded hydroxyl groups, which act as a heat-sink prior to ignition.
Smoke Suppressant - Also during combustion, ALCOA White Hydrates minimize smoke generation and in itself results in no toxic off-gases.
Non-Toxic -ATH is inately non-toxic and inert and therefore safe to handle.
Electrical Properties - High purity levels result in good arc and track resistance and low current leakage.
Abrasive Properties - ATH is a mild abrasive and emboding agent.
Versatile - ATH is free-flowing easy to handle and can be used in many formulations.
C-231 - C31 ground to a particle size distribution to achieve optimum particle packing and lowest viscosity versus other ground grades. |
