Bromobutyl Rubber Linings


Bromobutyl is a derivative of the halobutyl family, which is structurally similar to chlorobutyl rubber and produced through the same halogenation process: Brominated (BIIR) to Chlorinated (CIIR). By using the brominated process allows the same workability in the lining as a chlorobutyl.   The Bromobutyl polymer will exhibit stronger physical characteristics over Chlorobutyl. Bromobutyl Linings are either blended with Natural Rubber for ease of application or made pure in polymer content, which means there is no other polymer in the formulation which gives the lining stronger permeation and heat resistance.



•    Tight knitting of the molecular cross link which results in an extremely low permeability rate.

•    Low glass transition temperature

•    Wide vulcanization versatility

•    Fast cure rates

•    Higher Heat Resistance

o   Other Bromobutyl linings have a maximum heat resistance to 121°C as to the pure bromo can run at a constant temperature of 127°F and handle spikes up to 150°C

•    Stronger bond strength to substrates

•    Excellent Oxidation / Ozone Resistance

•    Good Abrasion Resistance



Common uses of Bromobutyl linings are:

– Scrubber Towers

– Piping,

-Storage Vessels

– Chutes

– Thickeners / Clarifiers
