UP FOR SALE IS 1/4" VIOTN 70A (FLUOROELASTOMER) BALLS - 10 PCS Viton 70A Fluorocarbon (FKM) Fluorocarbon elastomers are highly fluorinated, carbon backboned polymers used in applications to resist harsh chemical and ozone attack with a thermal stability to 500°F (262°C). Fluorocarbons also offer low compression set and excellent aging characteristics. FKM elastomers provide excellent service in oil, gasoline, hydraulic fluids, hydrocarbon solvents and extended fuels. The fluorine on the elastomer backbone provides the relative inertness of FKM elastomer. Generally speaking, with increasing fluorine content, resistance to chemical attack is improved while low temperature characteristics are diminished. There are, however, a few specialty grade fluorocarbons that can provide high fluorine content with low temperature properties. • Outstanding corrosive fluid resistance • Low compression set • Excellent seal compounds • Low outgassing Tensile Elongation Oil Aging Volume Swell (Change %) 70hr at 150°C/302°F Fuel Aging Volume Swell (Change %) 70hr at 23°C/73°F Compound Hardness Shore A MPa psi (%) IRM 901 IRM 903 Ref fuel B Ref fuel C 514AD 70 10.3 1500 200 +1 +4 +2 +3 FREE SHIPPING ANYWHERE IN THE US !!!
