to 82°C).
EPDM
is a general purpose elastomer with good resistance
to many acids and bases. Temperature range -40°F
to 280°F (-40°C to 138°C).
FKM
is an elastomer with good corrosion resistance to a
wide variety of chemicals. Temperature range -40°F
to 350°F (-40°C to 177°C).
Most of the above elastomers are available in FDA
