Product Description

IOTA 2056 HTV Ethyl Silicone Rubber" is a diethyl silicone rubber obtained by introducing ethyl groups onto the side chains of dimethyl polysiloxane. 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.
Additionally, diethyl silicone rubber possesses a constant elastic modulus and constant damping factor, making it a critical raw material for damping and vibration reduction in precision electronic devices.
