Flurine® 26120 and 26140 are high Mooney Fluoroelastomer, which is comprised of vinylidene fluoride (VF2) and hexafluoropropylene (HFP), frequently used in many industries including automotive, fluid power, appliance and chemical industries. It has excellent mechanical strength, good demoulding properties and low compression set. It is resistant to oils, fuels, aliphatic series, aromatic hydrocarbons, lubricants, and most mineral acids.
