Ethyl silicone rubber is a high-performance silicone rubber material made by introducing ethyl groups onto the side chains of dimethylpolysiloxane. This structural modification imparts distinctly different properties compared to traditional silicone rubbers, particularly excelling in low-temperature resistance. The introduction of the ethyl group disrupts the crystalline structure of the silicone rubber, resulting in an impressive glass transition temperature as low as -147°C, making it one of the best silicone rubbers for low-temperature performance.

This exceptional low-temperature resistance makes ethyl silicone rubber widely applicable in specialized fields such as cryogenic equipment, high-latitude regions, deep-sea exploration, aerospace, and aviation. It maintains stable physical properties even in extreme low-temperature environments, ensuring that equipment and materials continue to function properly without degradation due to cold. In high-altitude cold regions, it helps ensure that devices and materials operate reliably, even under harsh cold conditions.
