LR5853/90 - High performance

LR5853/90 is an FKM tetrapolymer-based synthetic elastomer with a high fluorine content.

It has enhanced fluid resistance, especially to methanol and gasoline-based blends that adversely affect other fluoroelastomers.

Temperature capability is 0°C (+32°F) to +230°C (+446°F), and its nominal hardness is 90 IRHD. As this grade stiffens below -5°C (+23°F), our FR25 and LR6316 compounds are recommended for lower temperature use.
