Silicone rubber is widely used in the field of medical devices due to its superior biocompatibility and various special properties. The following is practical knowledge of silicone rubber in medical devices.

1. Biocompatibility Silicone rubber has good biocompatibility with human tissues and will not cause allergic reactions or other adverse effects. Therefore, silicone rubber is often used to manufacture seals, catheters, artificial organs, etc. for medical devices.

2. Flexibility and elasticity
Silicone rubber has excellent flexibility and elasticity, making it suitable for manufacturing sealing components in medical devices. This characteristic makes silicone rubber widely used in medical instruments such as syringes, catheters, and pacemakers.

3. High temperature and chemical resistance
Medical devices often require sterilization under high temperature and high pressure conditions, and the high temperature resistance of silicone rubber makes it an ideal material. Meanwhile, its chemical resistance also ensures that medical devices are not corroded by chemicals during use.

4. Sealing performance
Silicone rubber has excellent sealing performance, which can prevent external environmental pollution inside medical devices. This makes silicone rubber widely used in the manufacturing of key components such as medical sealing rings and valves.

5. Wear resistance
Medical devices often require long-term use, and the wear resistance of silicone rubber makes it widely used in key parts of these instruments, such as the handle and control lever of surgical instruments.

Overall, the multiple advantages of silicone rubber in the field of medical devices make it one of the preferred materials for manufacturing medical devices.
