Common Sheet Packing Polymers
|
• Butyl (IIR / isobutyl-isoprene):
Excellent weathering and dialectic
properties with low air permeability.
Good physical properties. Poor
resistance to petroleum-based fluids.
TEMP: -30°F to +212°F> |
• Nitrile (NBR / Buna-N / butadiene-
acrylonitrile): Excellent resistance
to petroleum-based fluids. Good
physical properties.
TEMP: -40°F to +200°Fl |
• EPDM (ethylene-propylene diene):
Excellent ozone, chemical, heat and aging
resistance. Poor resistance to petroleum-
based fluids.
TEMP: -40°F to +250°F |
• Silicone (SI / Dimethyl-
Polysiloxame): Excellent high and
low temperature properties, fair
physical properties.
TEMP: -80°F to +500°F |
• Hypalon® (CSM / chloro-sulfinated
polyethylene): Excellent ozone,
weathering, and acid resistance. Good
abrasion and heat resistance. Fair
resistance to petroleum-based fluids.
TEMP: -20°F to +170°F |
• SBR (Styrene Butadiene Rubber):
Excellent abrasion resistance and
low temperature properties.
TEMP: -20°F to +180°F |
• Natural Rubber (NR / Gum Rubber):
Excellent physical properties, including
abrasion and resistance. Good flexibility
at low temperature. Poor resistance to
petroleum-based fluids.
TEMP: -20°F to 180°F |
• Urethane (polyurethane): Good
aging and excellent abrasion, tear
and solvent resistance. Poor high
temperature properties.
TEMP: -58°F to +180°F |
• Neoprene (CR / polychloroprene):
Good weather resistance and good
inherent flame resistance. Moderate
resistance to petroleum-based fluids.
Good physical properties.
TEMP: -20°F to 190°F |
• Viton® (FPM / hexafluoro-
propylene vinylidene fluoride):
and Excellent oil- air- resistance at
both low and high temperatures.
Very good chemical resistance.
TEMP: -20°F to +450°F |
