Latest Patents

One of Takasaki's latest inventions is a natural rubber-containing thermoplastic resin composition. This composition features a graft copolymer obtained by graft-polymerizing a vinyl monomer mixture that includes at least one aromatic vinyl monomer to a rubbery polymer. The formulation is uniquely designed to incorporate natural rubber, which constitutes 10 to 70% by mass of the composition, with synthetic rubber making up 30 to 90% by mass. This innovative approach ensures that the particles of natural rubber contain at least 5% by mass of natural rubber articles with a size of 1.0 micrometer or larger, leading to enhanced performance attributes.

Another noteworthy patent is for a table tennis ball and table tennis ball-use thermoplastic resin composition. This invention directly addresses the demand for high-quality table tennis balls that replicate the playing characteristics of traditional celluloid balls, yet avoids the use of celluloid itself. The patented composition boasts excellent mechanical properties, with a flexural modulus of 1650 MPa or more, a Charpy impact strength exceeding 20 kJ/m, and a density of less than 1.20 g/cm³. The resulting table tennis ball weighs between 2.0 to 3.5 grams and has a diameter of 39.0 mm or more.
