High strength extreme low temperature silicone is a specialized silicone rubber formulation engineered to maintain excellent mechanical properties (like tear and tensile strength) even at extremely low temperatures, typically as low as -100°F (-73°C) or colder. It combines durability, elasticity, and chemical resistance with the ability to remain flexible and resilient in frigid environments.
Advantages
-
Extreme Low Temperature Flexibility: Unlike standard silicones that may become brittle in sub-zero temperatures, these grades remain soft, pliable, and functional.
-
High Strength: Enhanced tensile strength (often >1000 psi), tear resistance, and elongation make it ideal for mechanically demanding applications.
-
Wide Temperature Range: Typically functions from -100°F to +450°F (-73°C to +232°C), with some formulations extending even wider.
-
Resilience: Excellent rebound and compression set resistance even after prolonged cold exposure.
-
Weather and UV Resistance: Performs well outdoors in arctic or aerospace conditions.
-
Chemical Resistance: Resists many oils, solvents, and fuels.
Applications
-
Aerospace seals and gaskets for aircraft exposed to high altitudes and extreme climates.
-
Cryogenic equipment seals (e.g., for LNG or space applications).
-
Military-grade enclosures, boots, and covers.
-
Arctic or deep-sea exploration equipment.
-
Cold storage/freezer door gaskets.
High strength extreme low temperature silicone excels where conventional elastomers would fail due to brittleness or cracking in the cold — while also delivering superior mechanical performance.
