20090029171 | New Functional Additive in Polymers - New functional additive in polymers comprised of micronized diatomite filler product, methods of producing the new functional additive in polymers, and methods of use thereof are provided. The new functional additive in polymers has, for example, a small median particle size (for example, less than 10 microns) and a small top particle size (for example, less than 20 microns), and a high blue light brightness (for example, higher than 84). The new functional additive in polymers may be used in a variety of applications such as reinforcement filler in polymers and anti-block filler in plastic films. | 01-29-2009 |
