Chemical Resistance |
Exceptional resistance to a wide range of chemicals, including strong acids, bases, and solvents. |
Excellent resistance to oils, fuels, and some acids but generally less resistant to strong bases and certain chemicals compared to FEPM. |
Resistance to Strong Bases |
Superior resistance, ideal for high pH environments. |
Less effective, limiting its use with alkaline substances. |
Cost-Effectiveness |
More cost-effective in the long run due to durability and broader chemical compatibility. |
Lower initial cost, but overall value must consider potential for replacement and performance limitations. |
Temperature Resistance |
Effective up to approximately 230°C (446°F), varying by formulation. |
Handles temperatures up to 250°C (482°F), depending on the specific type of FKM. |
Application Suitability |
Suitable for harsher environments like chemical processing, with exposure to a wide range of chemicals. |
Favored in automotive, aerospace, and oil & gas for its resistance to fuels, oils, and some acids. |
Weathering and Aging Resistance |
Excellent resistance to ozone, UV light, and weathering. |
Good resistance to weathering and aging, maintaining performance over time. |
