Parker’s Polychloroprene 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.
• Heat resistance
• Up to approximately 121°C (250°F)
• Cold flexibility
• Down to approximately -40°C (-40°F)
• Chemical resistance
• Paraffin based mineral oil with low DPI, e.g. ASTM oil No. 1
• Silicone oil and grease
• Water and water solvents at low temperatures
• Refrigerants
• Ammonia
• Carbon dioxide
• Improved ozone, weathering and aging resistance compared with nitrile
• Limited compatibility
• 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)
• Used for General Purpose
*Custom sizes and coatings/markings are available upon request. Contact Parker O-Ring Division at 859-269-2351 for design and pricing assistance.
