| 摘要 |
<p>TITLE Use Of Iron Oxide Pigments In A Polymethyl Methacrylate Article A dispersion of iron oxide pigments, selected according to particle size to avoid interference with desired properties is added to a polymerizable acrylic composition containing alumina trihydrate as filler. This mixture is cured to form a filled polymeric structure containing 15 to 80% by weight polymethyl methacrylate and 20 to 85% by weight alumina trihydrate with a pleasing uniform color, maintaining desired properties of machinability, translucency and visual depth.</p> |
