Title: Shigemasa Suzuki: Innovator in Polyarylene Sulfide Resin Compositions
Introduction
Shigemasa Suzuki is a notable inventor based in Ichihara, Japan. He has made significant contributions to the field of materials science, particularly in the development of polyarylene sulfide resin compositions. With a total of 5 patents to his name, his work has had a considerable impact on the encapsulation of electronic parts.
Latest Patents
One of his latest patents is a polyarylene sulfide resin composition specifically designed for electronic parts encapsulation. This innovative composition includes (A) from 20 to 35% by weight of a polyarylene sulfide resin, (B) from 60 to 75% by weight of silica, and (C) from 1 to 10% by weight of an elastomer. It also contains (D) from 0.05 to 1.2 parts by weight of an epoxysilane and/or (E) from 0.1 to 3 parts by weight of an epoxy resin, both relative to 100 parts by weight of the total amount of components (A), (B), and (C). This composition exhibits excellent PCT and TCT acceptable quality, good fluidity, and maintains the intrinsic properties of ordinary PAS resin. It is particularly advantageous for sealing electronic parts, as it prevents deformation of bonding wires and package breakdown.
Another significant patent by Suzuki is a polyarylene sulfide resin composition that comprises (A) from 20 to 34% by weight of a polyarylene sulfide with a melt viscosity of 150 to 800 poises, (B) from 66 to 80% by weight of spherical silica with a mean particle size of 0.3 to 10 µm, and (C) from 0 to 12% by weight of whiskers. The total of the spherical silica and whiskers falls between 66 and 80% by weight. This composition is known for its well-balanced physical properties, including dimensional accuracy and mechanical strength, making it suitable for precision members such as optical fiber connector ferrules.
