## Description

Nitrile is the combination of butadiene and acrylonitrile. Butadiene provides elasticity and low temperature flexibility, resistance to heat, chemicals and oxidation. Acrylonitrile provides hardness, tensile strength and creates resistance to abrasion, fuel and oil. Advantages: Excellent tensile strength, abrasion, tear and compression resistance. It is used in water and steam applications (below 212°F), petroleum oils and fuels, silicone oils and greases, propane, ethylene glycol, butane, vegetable, mineral oils and greases, and dilute acids. Disadvantages: Low resistance to ozone, sunlight and weathering. Incompatible with benzene, toluene, xylene, halogen derivatives (carbon tetrachloride, trichloroethylene), ketones (MEK, acetone), phosphate ester hydraulic fluids (Skydrol, Pydraul), strong acids and glycol.

## Features

- Hardness: 90 Durometer
- Material Type: Nitrile, Buna-N, NBR
