The waterproof neoprene O-ring neoprene sealing ring can release a substance that functions as a flame retardant when ignited. Therefore, although it can be ignited by direct flame, it will immediately self-extinguish once the open flame is disconnected. The flame retardancy of this plastic is good among general-purpose plastics. Due to its good bonding properties, neoprene is widely used as an adhesive. Neoprene-based adhesives account for about 80** of plastic adhesives, and their advantages include high bonding strength, wide application range, anti-aging, solvent resistance, acid and alkali resistance, ductility, and ease of use (generally without the need for vulcanized rubber).
