What is CR (Chloroprene rubber):

O-rings from Neoprene rubbers are homopolymers of chloroprene (chlorobutadiene) and functional to the earliest synthetic rubbers used to produce seals. CR O-rings are not useful in environments with aromatic and oxygen-rich solvents. Different compositions can be used to form Neoprene for operating temperatures from -40 °C to + 110 °C.

The advantage of CR O-rings:

  • Good resistance to bending cracks
  • Good aging properties in ozone and weather environments
  • Operating temperatures from -40 °C to + 110 °C

The disadvantage of CR O-rings:

  • Poor resistance to petroleum-based lubricants
  • Poor resistance to oxygen
