Neoprene O-Ring

Properties of Neoprene O-Rings

 Neoprene O-Rings are also termed as chloroprene or CR. Neoprene is multi-purpose elastomer which yields a balanced combination of properties. It is unusual that an elastomer is moderately resistant to both petroleum oils and weather i.e. ozone, UV, oxygen. This property qualified neoprene uniquely for certain sealing application where various other materials would be not satisfactory.

Various properties of Neoprene O-Rings are:

  • Neoprene has good physical strength along with abrasion and flexes cracking resistance.
  • Neoprene works well if an O-Ring is needed for gas permeation.
  • Elastomers are either resistant to deterioration from exposure to petroleum based lubricants or oxygen. Neoprene possesses limited resistance to both that accounts for desirability in seal application for refrigerator.
  • Neoprene has excellent adhesion qualities that can be successfully bonded to metal.
  • Neoprene seals greater resistance to fire than hydrocarbon based rubber.
  • Neoprene O-Ring has a broad temperature range and can be used in various general service applications.
  • Neoprene is resistant to refrigerators, ammonia, Freon, silicon, oils, water, ozone, vegetable oil, alcohol and low pressure oxygen.
  • Neoprene also has good resistance to water and water solvents at low temperature.
  • Neoprene is not suitable for environment that contains polar solvents, chlorinated hydrocarbon or aromatic hydrocarbons.

 Temperature range of Neoprene O-Rings is between -40o C and 1210 C
