Title: Tamotsu Matsubara: Innovator in Polyolefin Compositions
Introduction
Tamotsu Matsubara is a notable inventor based in Chiryu, Japan. He has made significant contributions to the field of materials science, particularly in the development of polyolefin compositions. With a total of 4 patents to his name, Matsubara's work focuses on enhancing the properties of polyolefin materials for various applications.
Latest Patents
Matsubara's latest patents include a polyolefin composition containing cellulose fibers and a deodorizer. This innovative composition comprises polyolefin, vegetable fibers mainly composed of cellulose, and a deodorizer selected from a combination of a metallic soap and an amine antioxidant, activated carbon, zeolite, and a phosphorus compound. The inclusion of the deodorizer ensures that the polyolefin composition has substantially no odor while maintaining its mechanical properties. This makes it particularly suitable for car parts that require high mechanical strength and minimal odor, such as unit cases of air conditioners.
Another significant patent is the polyolefin-base resin composition, which includes a vegetable fibrous material in fiber form containing cellulose as a major constituent and a high flow rate polyolefin-base resin with a melt index of 20 to 100. This invention addresses the poor processability of conventional polyolefin-base resin compositions that incorporate vegetable fibrous materials. By utilizing this resin, it has become possible to produce large-sized articles with small wall thicknesses through injection molding while retaining desirable mechanical characteristics.
