EXXON Bromobutyl
|
As EXXON Bromobutyl has the predominantly saturated backbone of butyl, it has
many of the attributes of the butyl molecule:
-
Low permeability to air, gases and moisture
-
Vibration damping
-
Low glass transition temperature
-
Resistance to ageing and to weathering from atmospheric exposure
-
Wide vulcanization versatility
-
Fast cure rates
-
Processing safety: no nitrosamines or nitrosamines precursors
ExxonMobil Chemical offers a range of polymer viscosities and cure responses,
reflecting adjustments in functionality and additives content. EXXON
Bromobutyl is structurally similar to EXXON Chlorobutyl.
