Chloroprene (Neoprene)

Neoprene (-40º to +250ºF) or (-4.44°C to +121°C) is reasonably priced and features good resistance 

to petroleum oils, ozone, sunlight and oxygen aging, relatively low compression set, good resilience 

and outstanding physical toughness. It is the preferred sealing material for the refrigeration industry 

because of its resistance to ammonia and Freon®.
