Ethylene Propylene (EMP, EPDM) (EPR)
  • Excellent resistance to Skydrol® fluids used in commercial aircraft hydraulic systems. Also, recommended for hot water, steam, and phosphate ester type hydraulic fluids. Also resistant to some acids, alkalies, and ozone. Not recommended for petroleum fluids or diester lubricants. Temperature range: -65° to +300°F.

PTFE
  • White thermoplastic fluoroethylene resin offers a combination of qualities not found in any other material-chemical inertness, heat resistance, low friction, dialectric strength, weatherability, zero water absorption, toughness, and flexibility. Temperature range: -65° to +500°F.

Aflas®
  • Advantageous combination of high temperature, chemical and electrical resistance properties. Recommended for oils and lubricants, hydraulic and brake fluids, transmission and power steering fluids, sour oil and gas (H2S), amine corrosion inhibitors, ozone, steam, acids, bases, alcohols, and variety of other chemicals. Temperature range: -20° to +400°F. (+600°F short term).

Urethane (Polyurethane)
  • Resistant to petroleum oils, hydrocarbon fuels, oxygen, ozone, and weathering. Particularly recommended for hydraulic systems where high pressures, shock loads, wide metal tolerances, or abrasive contamination is anticipated. Not recommended for acids, ketones, and chlorinated hydrocarbons. Some urethanes are also sensitive to water and humidity. Temperature range: -65° to +200°F.
