Worried that medical sealing rings might crack during high-temperature sterilization? Choosing the right silicone sealing ring is the key

Medical-grade high-temperature sterilization and anti-cracking solution

The sealing rings in medical equipment play a core role in sealing and preventing leakage. High-temperature sterilization (such as steam sterilization and dry heat sterilization) is a necessary step to ensure the sterility of medical supplies. However, many medical institutions are troubled by the cracking and deformation of sealing rings after high-temperature sterilization — which not only affects the sealing performance of the equipment but may also cause medical hidden dangers. In fact, choosing the right适配的 silicone sealing ring can easily overcome this problem.

High-quality medical silicone sealing rings need to be made of medical-grade addition-cured silicone. This material does not contain small molecular volatile substances. Under the repeated action of 134℃ steam sterilization and 180℃ dry heat sterilization, there will be no molecular chain breakage, and it can maintain stable elasticity and sealing performance. At the same time, the production process must strictly follow the ISO 10993 biocompatibility standards, pass the tests for no vulcanizing agent residues and no peculiar smell, and prevent pollution in the medical environment.

In terms of craftsmanship, the secondary vulcanization process (180℃ × 2h) is adopted to completely remove the residual low-molecular substances inside the product and improve the anti-aging performance; the cross-sectional design of the sealing ring must match the equipment slot to avoid cracking due to uneven force during sterilization caused by size deviation. Before leaving the factory, it also needs to undergo multiple simulated high-temperature sterilization tests to ensure that there are no cracks, deformation, swelling and other problems after 500 sterilization cycles.

The core of medical sealing rings not cracking during high-temperature sterilization lies in the medical-grade nature of the raw materials and the control of the craftsmanship.
