Product Description

Ethyl Silicone Rubber IOTA 2056 GUM

IOTA 2056 GUM 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.

Q: What is ethyl silicone rubber?
Answer: Ethyl silicone rubber is a kind of silicone rubber that contains ethyl groups in its molecules. It is polymerized from ethylsilane monomer and is an elastic, high temperature and chemical resistant synthetic rubber material.

Q: What are the main properties of ethyl silicone rubber?
Answer: Ethyl silicone rubber generally has excellent high temperature resistance, chemical stability, electrical insulation properties, aging resistance and softness, and is suitable for applications in a wide temperature range.

Q: What are the main uses of ethyl silicone rubber?
Answer: It is often used as seals, insulation materials, lubricants, softeners and rubber products, especially in applications requiring high temperature stability and chemical inertness.

Q: How is ethyl silicone rubber different from other silicone rubbers?
Answer: The ethyl groups in ethyl silicone rubber are different from the different groups in other silicone rubbers. This special structure may result in slightly different physical or chemical properties.

Q: What are the processing and application methods of ethyl silicone rubber?
Answer: Ethyl silicone rubber can usually be processed through extrusion, calendering, injection molding, etc., and can be made into sheets, tubes or coatings as needed and used in different fields.

Q: How safe is ethyl silicone rubber environmentally?
A: Ethyl silicone rubber is generally considered to have high environmental safety, but its specific uses and applications need to be evaluated according to local regulations and standards.
