Latest Patents
Coverdell's latest patents include the "High Modulus Polyimide Blend" and the "Adhesiveless Aromatic Polyimide Laminate." The High Modulus Polyimide Blend is an intimate polyimide blend that is prepared by chemical conversion. It contains from 25 to 50 weight % of a first polyimide derived from 90 to 100 mole % of 3,3', 4,4'-biphenyltetracarboxylic dianhydride, and from 50 to 75 weight % of a second polyimide derived from pyromellitic dianhydride. This blend provides blister-free films with high modulus and low thermal expansion coefficients, making it suitable for electronics applications. The Adhesiveless Aromatic Polyimide Laminate, on the other hand, is composed of multiple aromatic polyimide film layers containing from 400 to 10,000 ppm of tin. These layers are superimposed and directly bonded to each other without the use of adhesives, allowing for applications in thick film products such as punched gaskets, washers, and circuit boards.
