Chloroprene, also know as Neoprene, was the
first synthetic rubber developed com¬mercially 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 base 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 com¬pared
with NBR.
Limited compatibility
• Naphthalene based mineral oil (IRM 902 and IRM 903
oils).
• Low molecular aliphatic hydrocarbons (propane, butane,
fuel).
• Glycol based brake fluids.
Not compatible with:
• Aromatic hydrocarbons (benzene).
• Chlorinated hydrocarbons (trichloroethylene).
• Polar solvents (ketones, esters, ethers, acetones).
