FlexKM: Premuim Fluorocarbon Performance
Engineers have long sought to specify high performance FKM polymers in components for their superior high temperature and hydrocarbon resistance, but were often stopped because of the high cost. Now Flexan has brought a solution to the market that answers the need for undiminished performance, but at a more competitive price – FlexKM.
FlexKM is a true fluorocarbon thermoset elastomer with material properties superior to nitrile and HNBR. FlexKM offers equal or superior performance at a substantially reduced price. In addition, it offers an adaptable polymer platform that can be custom compounded for additional hydrocarbon resistance and/or low temperature as needed.
Your customers demand:
- Hydrocarbon, fuel, and hydraulic fluid resistance
- Low and high temperature performance
- Acid, base, and salt water resistance
- Abrasion resistance
- Competitive pricing
FlexKM delivers on all fronts. Contact Flexan today to see how FlexKM can help you succeed on your next project.
Please see below for a sample of the impressive material properties FlexKM offers.
