TECNOFLONÂ® T 538 is a low viscosity fluoroelastomer terpolymer with 68.5% fluorine content. TecnoflonÂ® T 538 has been designed and synthesized with a patented polymerization technology that assures improved processability and outstanding physical properties. TecnoflonÂ® T 538 does not contain curatives: therefore the proper levels of TecnoflonÂ® FOR M1 and TecnoflonÂ® FOR M2 must be added to achieve the required properties. TecnoflonÂ® T 538 exhibits the chemical resistance typical of fluoroelastomer terpolymers. It is well suited for applications requiring better chemical resistance and/or long term heat resistance compared to fluoroelastomer copolymers.Features: Good Chemical Resistance; Good Heat Aging Resistance; Good Processability; High Heat Resistance; Low Viscosity; TerpolymerUses: Belts/Belt Repair; Blending; Gaskets; Hose; Profiles; Seals; Sheet; Valves/Valve PartsAdditional Properties: Fluorine Content - 69 %Information provided by Solvay Specialty Polymers.
