also known as isobutylene-isoprene rubber (IIR), is a synthetic rubber that is known for its exceptional impermeability to gases, excellent resistance to heat, weathering, and chemicals. Here are some key characteristics and common uses of butyl rubber.
Butyl rubber has one of the lowest gas permeability rates among rubber materials, making it ideal for applications requiring airtight seals or barriers. It is used extensively in tire inner liners and inner tubes.
Weather and UV Resistance:
Butyl rubber exhibits good resistance to sunlight (UV), ozone, and weathering, making it suitable for outdoor applications.
It is highly resistant to a wide range of chemicals, acids, and bases, which makes it useful for applications in contact with corrosive substances.
Butyl rubber can withstand relatively high temperatures without significant degradation.
It remains flexible at low temperatures, making it suitable for applications in cold environments.
It has good electrical insulation properties, which can be important in certain applications.
of Butyl Rubber:
Gaskets and O-rings
Butyl rubber’s unique combination of properties makes it valuable in a wide range of applications where the impermeability to gases, weather resistance, and chemical resistance are essential.
