Fluoroelastomer—Elkhart Rubber

In many applications, AFLAS outperforms other elastomers because of the following characteristics (1) High temperature resistance (400 F long term 550-h°F shorter term) (2) Resistance to a wide range of chemicals (including acids, bases, steam, sour (H2S) oil and gas with amine corrosion inhibitors, oils and lubricants, hydraulic fluids of all types, brake fluids, bleaches, oxidizing agents, alcohol, etc.) (3) Durable physical properties (4) Excellent electrical resistance-Dielectric constant at 60 Hz of 2.5. 

The following chart provides an indication of the chemical resistance of AFLAS. Since temperature, concentrations, mixtures, and elastomer compound selection can affect performance, this chart provides guidelines only. Unless otherwise noted, the tests were run on a 75 Shore A carbon black filled AFLAS 150P formulation with the following properties

Where available, the chart shows the change in hardness (in Shore A points) and volume as well as the percentage of original tensile strength and elongation retained after immersion in the test fluid under the time and temperature conditions denoted. In other instances, volume change only is shown.
