Latest Patents

Among his most recent innovations, Kobayashi has developed an acrylic rubber composition aimed at providing excellent heat resistance. This composition offers a remarkable balance between the tensile strength and elongation residual ratios after heat aging when transformed into vulcanized products. His invention includes a specific formulation involving 100 parts by mass of an alkyl acrylate, combined with 10 to 100 parts by mass of an alkyl methacrylate and 0.5 to 4 parts by mass of a crosslinkable monomer. The selection of alkyl methacrylates and alkyl acrylates, such as methyl, ethyl, and n-butyl varieties, enhances the properties of this innovative material.

Furthermore, Kobayashi has patented a system for permeation printing a plastic body, which is especially beneficial for wear-resistant applications, such as keyboard key tops. This process employs a unique ink featuring a medium with a solubility parameter between 8.5 to 11.5 (cal/cc) and involves the steps of printing the article and using a heating and covering device to ensure the ink permeates effectively into the plastic. This invention significantly improves the durability and aesthetic of printed surfaces.
