  • Germ-repellent silicone rubber and preparation method and application thereof
    Patent number: 11945950
    Abstract: The present invention provides a germ-repellent silicone rubber comprising: a silicone rubber substrate and a germ-repellent active ingredient incorporated therein; wherein, the silicone rubber substrate includes polydimethylsiloxane; the germ-repellent active ingredients include poly(ethylene oxide) and silicone oil or their derivatives. The disclosed germ-repellent silicone rubber reduces the bacterial growth by inhibiting their adherence to the surface instead of killing them, does not contribute to super bacteria formation nor cause skin irritation.
    Type: Grant
    Filed: October 22, 2021
    Date of Patent: April 2, 2024
    Assignee: Hongrita Plastics Ltd.
    Inventors: Xiaonan Huang, Xianqiao Liu, Chun Kit Choi
