The term silicone covers a large group of
materials in which vinyl-methyl-silicone (VMQ) is often the
central ingredi¬ent. Silicone elastomers as a group have
relatively low tensile strength, poor tear and wear resistance.
However, they have many useful properties as well. Silicones
have good heat resistance up to 232°C (450°F), good
cold flexibility down to -59°C (-75°F) and good ozone
and weather resistance as well as good insulating and physi¬ologically
neutral properties.
Cold flexibility
• Down to approximately -57°C (-70°F).
Compatible with
• Water, alcohol, glycol and certain ketones (acetone).
• Non-mineral oil based brake fluid.
• Silicone oil and grease.
• Diluted water solutions, weak acids.
Not compatible with:
• Mineral oils
• Petroleum greases and fuels.
• Aliphatic hydrocarbons like benzene, toluene, xylol.
• Chlorinated hydrocarbons - such as chloroform, trichlo¬rethylene,
carbon tetrachloride.
• Oxidizing media like nitric acid, chromic acid, hydro¬gen
peroxide, chlorine, bromine.
