20090036580 | USE OF ORGANOCLAY IN HDPE NANOCOMPOSITES TO PROVIDE BARRIER PROPERTIES IN CONTAINERS AND FILM - HDPE nanocomposite is made by mixing HDPE with organoclay. Such HDPE nanocomposite contains concentrations of organoclay less than 4 weight percent. Unexpectedly, using less organoclay than that conventionally recommended, results in superior oxygen and water vapor transmission rates for HDPE compounds. The HDPE nanocomposite is useful for packaging films and containers for food or other perishables. | 02-05-2009 |
20090186227 | STABILIZED POLYOLEFIN NANOCOMPOSITES - A heat stabilized polyolefin nanocomposite is disclosed, which contains metal scavengers to heat stabilize the nanocomposite. | 07-23-2009 |
20100036027 | THERMALLY STABLE THERMOPLASTIC VULCANIZATE COMPOUNDS - A high temperature thermoplastic vulcanizate is disclosed, which achieves its long term heat aging performance from a set of heat stabilizers, at least one of which stabilizes the thermoplastic phase and at least one of which stabilizes the elastomeric phase. Plastic articles made from the high temperature thermoplastic vulcanizate are also disclosed. The thermoplastic vulcanizate can be made by melt mixing or by dynamic vulcanization in an extruder. | 02-11-2010 |

20090117393 | NUCLEATED POLYPROPYLENE NANOCOMPOSITES - nuc-PP nanocomposite is made from the mixing of nuc-PP with olefin elastomer and organoclay, and optionally, a dispersion agent. Unexpectedly, processing properties such as higher melt flow, and performance properties such as higher toughness and higher stiffness, are obtained when compared with commercially available PP nanocomposite. | 05-07-2009 |
20090292055 | NANOCOMPOSITES COMPLIANT WITH REGULATORY REQUIREMENTS - A nanocomposite is made from melt-mixing of polyethylene with organoclay in the presence of a maleated polypropylene. Unexpectedly, the maleated polypropylene and polyethylene are sufficiently compatible to permit excellent dispersion of the organoclay in the nanocomposite. Because maleated polypropylene is compliant with U.S. Food and Drug Administration regulations, though maleated polyethylene is not, one can use nanocomposites of the present invention for articles to be in contact with human food. | 11-26-2009 |
20090303463 | WEATHERABLE POLYOLEFIN NANOCOMPOSITES - A method is disclosed concerning discovering how the use of an additive in a polyolefin compound affects the weatherability of that compound. Applying that technique, a weatherable polyolefin nanocomposite is disclosed, which contains UV stabilizers that filter wavelengths in a range influenced by presence of organoclay in the nanocomposite. | 12-10-2009 |
