As a material, Neoprene (Chloroprene) is specified for good resilience across a moderate temperature band, a balanced combination of oil and weather resistance. The compound resists moderate petroleum oil exposure, mild acids, and refrigerants and ammonia. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving aromatic hydrocarbons or chlorinated solvents call for a different compound.

You will find this material specified across marine equipment, transit and rail, and HVAC and refrigeration.
