Description

FVMQ offers excellent chemical resistance to dilute acids and alkalines, and non-polar fluids. they have high heat and oxidative stability, outstanding low temperature flexibility, and are resistant to heat, ozone and sunlight (UV). They also offer a similar wide operational temperature range, which is much wider than that of fluorocarbon rubbers.
