Butyl Rubber Instant

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 withstands most acids, alkalis, and polar solvents but is highly susceptible to petroleum-based oils, fuels, and hydrocarbon solvents. Common Applications butyl rubber

It offers excellent resistance to ozone, weathering, UV radiation, and heat aging. It has one of the lowest gas transmission

, 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 , also known as isobutylene-isoprene rubber ( IIR

It typically remains functional in a wide range from -40°C to 120°C (-40°F to 248°F).

It has superior vibration-damping and shock-absorption properties, making it useful in automotive and industrial mounts.
