Silicone Rubber Features:
Silicone rubber offers great resistance in extreme temperatures, being able to operate normally from -100°C to +250°C (-150°F to +480°F). At extreme temperatures, the tensile strength, elongation, tear strength and compression set can be far superior to conventional rubbers. This makes it one of the materials of choice in many extreme environments.
Caution: Generally, silicones are attacked by most concentrated solvents, oils, acids and dilute sodium hydroxide.
