Chloroprene Rubber (CR)
Chloroprene 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.
• Up to approximately 121°C (250°F).
• Down to approximately -40°C (-40°F).
• Paraffin based mineral oil with low DPI, e.g. ASTM oil No. 1.
• Silicone oil and grease.
• Water and water solvents at low temperatures.
• Carbon dioxide
• Improved ozone, weathering and aging resistance compared with nitrile.
• Naphthalene based mineral oil (IRM 902 and IRM 903 oils).
• Low molecular weight aliphatic hydrocarbons (propane, butane, fuel).
• Glycol based brake fluids.
Not compatible with:
• Aromatic hydrocarbons (benzene).
• Chlorinated hydrocarbons (trichloroethylene).
• Polar solvents (ketones, esters, ethers).
