Anti-aging neoprene O-rings Neoprene (CR) O-rings are commonly used in Freon R22 system software. Neoprene (CR) O-rings can be used to manufacture high-temperature resistant conveyor belts, cables, insulating sleeves, acid and alkali resistant rubber and plastic products, engineering sealing strips, road joint sealants, bridge rubber bearings, moisture-proof caps for cables in oil and gas fields, oil-resistant hoses for vehicles, and corrosion-resistant rubber and plastic products. They can also be used to produce moisture-resistant rubber and plastic products, weather-resistant products, flame-retardant products, various sealing products, gaskets, and neoprene adhesives.
