The newly developed IOTA 2056 GUM Ethyl Silicone Rubber series redefines performance standards for cryogenic elastomers through molecular structure innovation, emerging as a core material solution for extreme environments in aerospace and deep-sea exploration.
Ultra-Low Temperature Resistance
• Glass transition temperature as low as -147℃ (vs. -60℃ for conventional silicone rubber)
• Maintains elasticity in liquid nitrogen (-196℃) without brittleness
Constant Elastic Modulus & Damping Stability
• <5% modulus variation across -100℃ to 200℃
• Military-grade damping stability (GB/T 18258-2000)
Multi-Protection Performance
• Radiation/Ozone/Salt Spray corrosion resistant
