[0083] Silane Surface Treatment of Glass Bubbles

[0084] 1500 g of a 0.5% by weight aqueous solution of 3-aminopropyltriethoxysilane (commercially available under the trade designation "AMEO" from Evonik, Germany) was charged to a Ross mixer (available from Harbin, NY). Parker's Charles Ross & Son Company (Charles Ross & Son Company, Hauppauge, N.Y.)). Glass bubbles (available from 3M Company, St. Paul, MN, USA) under the trade designation "iM16k" were added slowly at a moderate mixing speed and a mixing time of 15 minutes. The glass bubbles were added in such a way that a coating quantity of 1.1% by weight was achieved. The resulting paste was poured into aluminum pans and dried overnight in a forced air oven at 80°C. The dried glass bubbles were screened through a 180 micron sieve to remove any lumps.

Description

technical field [0001] The present invention relates to polyolefin compositions comprising hollow glass microspheres with improved mechanical properties. Background technique [0002] Hollow glass microspheres having an average diameter of less than about 500 microns, also commonly referred to as "glass microbubbles," "glass bubbles," "hollow glass beads," or "glass balloons," are widely used, for example, as additives to polymer compositions Used in industry. Hollow glass microspheres are useful in many industries, for example, to reduce the weight of polymer compositions and to improve the processing, dimensional stability and flow characteristics of polymer compositions. Hollow glass microspheres have been incorporated into polypropylene composites for some applications. See, eg, US Patent 7,365,144 (Ka et al.). The need for lightweight solutions in the polymer industry eg for automotive applications has led to increasing interest in thermoplastic compounds comprising ...
