Post-pandemic high-frequency disinfection demands more durable medical devices. Mindray and Dow Inc. launched a new platinum-cured silicone rubber sealant resistant to repeated exposure to corrosive disinfectants (e.g., sodium hypochlorite, peracetic acid), reducing aging/cracking risks by 70%. Optimized siloxane backbone structures boost tear strength to 8MPa while maintaining biocompatibility. Trials in top-tier hospitals show respirator masks and catheter valves now last 9 months (vs. 6 months), saving >¥10M annually on consumables.
