Perfluoroelastomers (FFKM) are widely used in market segments which see hostile chemical and temperature environments, such as the Chemical Processing Industry, Aerospace, Semicon and Oil & Gas. The Perfluoroelastomer product portfolio from Dyneon utilises a broad range of polymer and cure technologies, enabling us to meet the demands of those market sectors.

The Dyneon product range includes the peroxide-curable 3M™ Dyneon™ Perfluoroelastomer PFE90Z and the high-temperature material 3M™ Dyneon™ Perfluoroelastomer PFE131TZ, having superior temperature resistance (continuous 316 °C).

However nitrile-curable Perfluoroealstomer compounds in general are not recommended when subjected to steam, water and nucleophiles at high temperatures.

Peroxide-cured materials have better resistance to these media but are limited in maximum temperature resistance (continuous 220 °C).

Due to harsher environments within the chemical processing industry, there is an increasing requirement for a single product that combines both benefits of overall excellent chemical resistance with a higher continuous operating temperature resistance (up to 275 °C).

Dyneon has overcome the technical challenges faced in combining both of these features into one single technology. Dyneon has developed such a product. The new development 3M™ Dyneon™ Perfluoroelastomer E-20658 is a proprietary, black, 75 Shore A compound with excellent chemical resistance and continuous operating temperature at 275 °C.
