Epichlorohydrin is available in two types:
the homopoly¬mer (CO) and the copolymer (ECO). Both CO
and ECO have good resistance to mineral oils, fuels and ozone.
The high temperature resistance is good. Compression set and
the tendency to corrode metal sealing faces increase at 150°C
(302°F). ECO has a good cold flexibility. CO has a high
resistance to gas permeability.
Heat resistance
• Up to approximately 135°C (275°F).
Cold flexibility
• Down to approximately -40°C (-40°F).
Chemical resistance
• Mineral oil and grease.
• Aliphatic hydrocarbons (propane, butane, fuel).
• Silicone oil and grease.
• Water at room temperature.
• Ozone, aging and weather resistant.
Not compatible with:
• Aromatic and chlorinated hydrocarbons.
• Ketones and esters.
• Non-flammable hydraulic fluids in the groups HFD-R
and HFD-S.
• Glycol based brake fluids.
