Latest Patents
One of Justin's latest patents is focused on processing aids for olefinic webs, including electret webs. This patent describes methods of preparing polymeric webs through hot melt blending of thermoplastic resins and processing aids. The processing aids include hindered amine N-substituted succinimide oligomers, which enhance the properties of the resulting webs. These webs can be produced in the form of films or non-woven fibrous webs, with non-woven microfiber webs being particularly useful as filtration media. Additionally, the processing aids function as charge-enhancing additives for the electret webs.
Another notable patent involves a method of making electret articles based on zeta potential. This method allows for the charging of a polymeric article that has a zeta potential of greater than or less than -7.5 millivolts. The article is charged by contacting it with an aqueous liquid that has specific pH and conductivity parameters. This innovative approach can significantly improve the electret performance of filtration articles.
