説明

<p>Continuous devulcanization technology for vulcanized rubber has the potential to greatly contribute to reducing environmental impact and realizing a circular economy. The continuous devulcanization process using a twin-screw extruder effciently devulcanizes vulcanized rubber by applying high internal pressure and shear strain to the vulcanized rubber, and the properties of the devulcanized rubber can be controlled by the reaction temperature, screw rotation speed, and the addition of devulcanizing agents and process oils. Devulcanized rubber can be re-vulcanized and has mechanical properties almost equivalent to those of virgin vulcanized rubber, making it possible to manufacture high-quality recycled rubber products. [br]In 2023, automotive rubber parts using this technology obtained the "ISCC PLUS Certifcation." This certifcation certifes the use of sustainable raw materials, making it possible to offer them to the market as products with high environmental value.</p>
