| 20080312362 | Method of Generating a Dispersion of Deagglomerated Barium Sulphate in Plastics or Plastics Precursors - The invention discloses a method of incorporating deagglomerated barium sulphate having an average primary particle size of less than 0.5 μm and coated with a dispersant into plastics or precursors of plastics, for example into polyols. The deagglomerated barium sulphate is dispersed in an organic solvent, the dispersion is incorporated into the plastic or the precursor of the plastic, and the solvent is evaporated off. | 12-18-2008 |

| 20100004352 | Method for the production of curable masses, containing coarse-scale and/or nanoscale, coated, de-agglomerated and preferably functionalized magnesium hydroxide particles, as well as of cured composites, containing de-agglomerated and homogenously distributed magnesium hydroxide filler particles - The present invention relates to a method for the production of curable masses, containing coarse-scale and/or nanoscale, coated, de-agglomerated magnesium hydroxide particles. More precisely, the present invention relates to a method for the production of curable masses, whereby coarse-scale and/or nanoscale, precoated magnesium hydroxide particles in an aqueous or organic solvent are treated with ultrasound or subjected to bead-mill grinding in the presence of a dispersant. After any drying that might be necessary, and renewed suspension/dispersion in an organic solvent, the magnesium hydroxide particles are worked into a component of a curable mass. Furthermore, the present invention is directed at a method for the production of a cured polymer material. Finally, the present invention makes available curable masses, polymer materials produced from them, particularly duroplastics or thermoplastics, as well as composite material containing curable masses or polymer materials produced according to the invention, as well as reinforcement agents. | 01-07-2010 |
| 20100011993 | Method for the production of coarse-scale and/or nanoscale, coated, de-agglomerated magnesium hydroxide particles - The present invention relates to a method for the production of coated magnesium hydroxide particles, whereby the individual primary magnesium hydroxide particles are coated. According to the invention, specific additives are added to the precipitation reaction for obtaining the magnesium hydroxide particles, in order to obtain these magnesium hydroxide particles in a coated state. Furthermore, a first method step of the present invention is directed at a method for the production of coarse-scale or nanoscale, coated magnesium hydroxide suspensions or dispersions. In a second method step, the coated magnesium hydroxide particles can be converted to de-agglomerated products either by means of bead-mill grinding or ultrasound and a dispersant. Finally, the present invention is directed at coated magnesium hydroxide particles, particularly nanoscale, coated magnesium hydroxide particles that can be obtained in this manner. | 01-21-2010 |
| 20100038817 | Device, production and method for thermoplastic polymers containing coarse-scale and/or nanoscale, coated, de-agglomerated magnesium hydroxide particles - A method and device for the production of thermoplastics containing coarse-scale and/or nanoscale, coated, de-agglomerated magnesium hydroxide particles that are supplied to the thermoplastic in the form of a dispersion or suspension in an aqueous or organic solvent, and mixed with the themoplastic. The thermoplastics filled with magnesium hydroxide particles demonstrate improved mechanical properties, particularly an improved modulus of elasticity and low brittleness. | 02-18-2010 |
