It offers excellent resistance to ozone, weathering, UV radiation, and heat aging.
It typically remains functional in a wide range from -40°C to 120°C (-40°F to 248°F). butyl rubber
It has superior vibration-damping and shock-absorption properties, making it useful in automotive and industrial mounts. It offers excellent resistance to ozone, weathering, UV
It has one of the lowest gas transmission rates among all rubbers, which is why it's used extensively in tire inner liners and tubes. It has one of the lowest gas transmission
It withstands most acids, alkalis, and polar solvents but is highly susceptible to petroleum-based oils, fuels, and hydrocarbon solvents. Common Applications
, also known as isobutylene-isoprene rubber ( IIR ), is a synthetic elastomer produced by copolymerizing isobutylene with a small amount of isoprene. It is highly valued for its exceptionally low gas and moisture permeability , making it the standard material for applications requiring airtight seals. Key Characteristics
