NOXTITE® FKM Fluoroelastomers
NOXTITE® FKM (FPM) grades cover a large range of materials available for automotive, chemical and industrial applications with bisphenol and peroxide curable copolymers as well as terpolymers. Our broad portfolio offers elastomers with a Tg of -30°C, but also grades for service temperatures up to 250°C, all available in different viscosities
Our Fluoroelastomers surpass the industry requirements for dynamic stability, extreme heat/cold exposure, fuel resistance and aggressive engine or transmission fluids.
