Latest Patents
One of Hikaru Shii's latest patents is focused on manufacturing a uniaxially drawn oriented polyolefin film for electric cable insulation. This film has a thickness ranging from 80 to 250 micrometers and is composed of a crystalline polyolefin with a melt index of 10 or more. The film incorporates 0.5 to 20 parts per hundred resin (phr) of unsintered polytetrafluoroethylene, which is uniformly dispersed in the crystalline polyolefin matrix. The film exhibits an apparent melt index value that is 1/4 to 1/10 of the crystalline polyolefin used, and it has a tensile Young's modulus of 2 x 10^4 kg/cm² or more. Additionally, the change in thickness of the film in dodecylbenzene at 100°C is limited to 10% or less. A method for manufacturing this film is also included in the patent.
Another notable patent by Shii involves a magnetic recording medium and the method of manufacturing it. This invention features a protective film created through plasma polymerization of organic compounds such as dibenzyl or diphenyl. This protective film is formed on a thin ferromagnetic film and is designed to provide high wear resistance and excellent anti-corrosion properties.
