Butyl polymers' unique combination of barrier properties, high damping,
resistance to ozone and heat aging make them ideal for use in many automotive
applications. The largest automotive applications for butyl polymers are heat
resistant hose and dynamic parts including body mounts.
EXXON
Chlorobutyl and EXXON Bromobutyl
are used in vibration control applications due to their high damping, fast
reversion-resistant cures and excellent aging properties, especially with
respect to hot flex fatigue. Compared to butyl, they can also be formulated to
have an intermediate level of oil resistance finding use in engine and
transmission mounts and automotive exhaust hanger formulations.
Exxpro
specialty elastomers combine the low permeability and high damping
properties of butyl rubbers with the environmental and aging resistance of
EPDM (ethylene propylene diene monomer) rubbers. Some of the benefits of
Exxpro specialty elastomers can be seen in the attached article on "Heat
Resistant Engine Mounts" (in progress).
The high heat resistance capabilities of EXXON Chlorobutyl and EXXON
Bromobutyl have resulted in their use in steam and hot water hose
applications. The fabricated hose consists of a tube that contains the water
or steam, a fabric or wire reinforcement and a cover for protection against
abrasion and weathering. The low compression set of chlorobutyl compounds and
their resistance to attack in a variety of environmental conditions lead to
their use in many types of gaskets.
