The polyethylene polymer contains additional
chlorine and sulfur groups. Chlorine gives the material resistance
to flame and mineral oil and also improves the cold flexibility.
Heat resistance
• up to 121°C (250°F).
Cold flexibility
• down to approximately -29°C (-20°F).
Chemical resistance
• Many acids.
• Many oxidizing media.
• Silicone oil and grease.
• Water and water solvents.
• Ozone, aging and weathering resistance.
Limited compatibility
• Low molecular aliphatic hydrocarbons (propane, bu¬tane,
fuel).
• Mineral oil and grease.
• Limited swelling in aliphatic oils (ASTM oil No. 1).
• High swelling in naphthene and aromatic base oils
(IRM 902 and IRM 903 oils).
• Polar solvents (acetone, methyl ether, ketone, ethyl
acetate, diethyl ether, dioxane).
• Phosphate-ester based fluids.
Not compatible with:
• Aromatic hydrocarbons (benzene).
• Chlorinated hydrocarbons (trichloroethylene).
