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, butane, 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)
