The reason why medical devices use flame retardants is mainly for safety and fire protection considerations. Flame retardant is a chemical substance that can inhibit the spread of flames. It can slow down the spread of fire, thereby giving people more time and opportunities to escape, and reducing casualties and property losses. In medical equipment, some electronic equipment or mechanical equipment may have the risk of fire due to electrical failure or other reasons. The use of flame retardants can effectively reduce this risk and ensure the safety and stability of medical work.
