Butyl rubber is a synthetic rubber derived from copolymerizing isobutylene with a small amount of isoprene. It is a type of elastomer that exhibits excellent resistance to heat, weathering, ozone, and chemical attack. Also known as polyisobutylene, butyl rubber is characterized by its high impermeability to gases and liquids, making it ideal for applications requiring air or liquid tight seals.
Butyl rubber possesses exceptional tensile strength, low gas permeability, and high flexibility, making it widely used in various industries. It finds extensive application in the automotive sector for manufacturing tires and tubes due to its unique combination of high wear resistance and low rolling resistance. Additionally, it is used in the production of conveyor belts, hoses, gaskets, and seals, where its sealing properties are critical.
The excellent heat resistance and electrical insulation properties of butyl rubber make it suitable for applications in the electrical industry, including cable insulation and coatings. It is also utilized in the construction industry for manufacturing waterproofing membranes, adhesives, and sealants.
The chemical resistance of butyl rubber makes it highly desirable for applications requiring resistance to corrosive chemicals, such as tank linings and flexible connectors for chemical processing equipment. It is also used in the medical field for producing gloves, adhesives, and seals.
Overall, butyl rubber is a versatile synthetic rubber widely employed in numerous industries that value its superior resistance to gas and liquid permeation, excellent durability, and reliability in a wide range of operating conditions.
