Talk about the material of the inflatable sealing ring of the waterproof electrical distribution box

The material of the inflatable sealing ring of the waterproof electrical distribution box needs to have excellent sealing performance, water resistance and corrosion resistance. Commonly used materials include:

1. Neoprene (NBR): It has excellent oil resistance, wear resistance and acid and alkali resistance, and is suitable for use in wet and greasy environments.

2. Fluorine rubber (FKM): It has excellent high temperature resistance and chemical corrosion resistance, and is suitable for use in high temperature and acid-base environments.

3. Nitrile rubber (NBR): It has excellent oil resistance, wear resistance and acid and alkali resistance, and is suitable for use in wet and greasy environments.

4. Polyurethane (PU): It has excellent elasticity and wear resistance, and is suitable for use in wet and greasy environments.

These materials have different characteristics and scope of application, and it is necessary to select the appropriate material according to the specific situation to ensure the airtightness and waterproof performance of the electrical distribution box.
