The introduction of ethyl groups disrupts the crystalline properties of silicone rubber, highlighting its cold resistance. Its lowest glass transition temperature reaches -147°C, making it the silicone rubber with the best low-temperature resistance. Diethyl silicone rubber serves as the foundational material for rubber products in low-temperature applications, such as cryogenic equipment, high-latitude and high-altitude cold regions, aerospace, aviation, and deep-sea exploration.
