Neoprenes
are homopolymers of chloroprene (chlorobutadiene) and were among
the earliest of the synthetic rubbers available to the seal manufacturers.
Neoprene
can be compounded for service at temperatures of -65 degrees +300
degrees F (-54 to +149 degrees C). Most elastomers are either
resistant to deterioration from exposure to petroleum lubricants
or oxygen. Neoprene is unusual in having limited resistance to
both. This, combined with broad temperature range and moderate
cost accounts for its desirability in many seal applications.
Chloroprene
is recommended for:
- Refrigerants
(Freons, ammonia)
- High
aniline point petroleum oils
- Mild
acid resistance
- Silicate
ester lubricants
Chloroprene
is not recommended for:
- Phosphate
ester fluids
- Ketones
(MEK, acetone)
