Neoprene was the first synthetic rubber developed commercially and exhibits generally good ozone, aging and chemical resistance. It has good mechanical properties over a wide temperature range. Improved ozone, weathering and aging resistance compared with nitrile rubber.
Both o-rings and gaskets can be made from Neoprene materials.
