Material Properties

NBR (Nitrile Butadiene Rubber) provides excellent resistance to:

• Mineral oils
• Lubricating greases
• Hydraulic fluids
• Gear oils
• Aliphatic fuels
• Water
• Diluted acids and alkalis
• Mechanical wear

Typical operating temperature range is approximately -30°C to +100°C, depending on the compound formulation and service conditions. NBR is generally not recommended for prolonged exposure to ozone, UV radiation or severe outdoor weathering.
