Antimony Trioxide
Microfine AO3 is a sub-micron particle size antimony trioxide with an average particle size of 0.3 microns. The product is predominantly senarmontite (cubic crystal form), with a high tinting strength and a bright white powder color.
Microfine AO3 finds application as a flame retardant, when used in combination with a source of halogen. In rigid and plasticized PVC compounds, the addition of controlled amounts of Microfine AO3 will confer excellent flame retardant properties. Microfine AO3 is especially recommended in coating applications where it¡¯s very fine particle size can give benefits of improved suspension stability, smoother surface finish and improved physical properties along with it¡¯s high white pigmenting power. Microfine AO3 also finds application in thermoplastic compounds where tensile and impact properties are critical or in very thin wall applications to improve surface finish and electrical properties.
The use of proper protective equipment is recommended. Excess exposure to the product should be avoided. Wash thoroughly after handling. Store the product in a cool, dry, wellventilated area away from incompatible materials. Unless stated, proper storage will permit usage of the product for 6 to 12 months from the date of receipt. For additional handling and toxicological information, consult the GLCC Material Safety Data Sheet. |
