The term silicone covers a large group of materials in which vinyl-methyl-silicone (VMQ) is often the central ingredient. 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 physiologically 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, trichlorethylene, carbon tetrachloride
• Oxidizing media like nitric acid, chromic acid, hydrogen peroxide, chlorine, bromine
