Common Elastomer Materials Overview

NBR Nitrile Rubber
Oil-resistant elastomer. Higher ACN reduces low-temp flexibility while improving tensile strength and abrasion resistance.
✔ Recommended
  • Petroleum-based oils
  • Water (≤100°C)
  • Alkaline solutions
✘ Avoid
  • Aromatic fuels
  • Strong acids
  • Ozone / Polar solvents
Typical Applications: Mineral oil, compressed air, hydraulic oils.
-30°C to 120°C
EPDM Ethylene Propylene
Excellent weathering, ozone, and chemical resistance. Good electrical insulation and ketone resistance.
✔ Recommended
  • Brake fluids
  • Steam (≤204°C)
  • Diluted acids/alkalis
✘ Avoid
  • Petroleum oils
  • Diester lubricants
  • Hydrocarbons
Typical Applications: Water, steam, compressed air, alcohols.
-50°C to 150°C
SILICONE VMQ
Excellent resistance to UV/ozone. Wide temperature range, non-toxic, and outstanding elasticity.
✔ Recommended
  • Engine oil
  • Dry heat / Ozone
  • Silicone grease
✘ Avoid
  • Petroleum fuels
  • Concentrated acids
  • Superheated steam
Typical Applications: Food/Medical, high-temp sealing, gases.
-70°C to 300°C
FKM Fluoroelastomer
Outstanding heat resistance and low gas permeability. Excellent ozone/weather resistance.
✔ Recommended
  • Chlorinated hydrocarbons
  • High vacuum
  • Petroleum oils
✘ Avoid
  • Hot water/steam
  • Amines
  • Brake fluids
Typical Applications: Aerospace, automotive, chemical seals.
-30°C to 275°C
HNBR Hydrogenated Nitrile
Superior mechanical strength and wear resistance. Bridges the gap between NBR and FKM with better heat and oxidation resistance.
✔ Recommended
  • Refrigerants (R134a)
  • Sour Gas (H2S) / Oil
  • Diluted acids
✘ Avoid
  • Polar solvents (Ketones)
  • Chlorinated hydrocarbons
  • Strong acids
