Latest Patents

Higashiguchi is credited with 1 patent: “Vinyl chloride type resin composition.” The invention describes a composition containing 100 parts by weight of vinyl chloride type resin and 25 to 200 parts by weight of plasticizer. The resin consists of 1 to 90 percent tetrahydrofuran-insoluble gel fraction, with the remainder being a tetrahydrofuran-soluble fraction.

The composition is intended to produce a rubbery elastomer with strong resistance to heat deformation, a matt finish, and a low compression permanent set. Despite its rubber-like properties, it can be molded and processed similarly to conventional thermoplastic resins. Potential applications include automobile interior sheets, packings, and tubes.
