The fibre reiforced ZX-750V5KF is moreimpact resistant than natural PEEK.So far, from 100 °C, the ZX-750V5T offers the best measuredwear resistance. ZX-750V5T is from 2000 % to 8000 % morewear resistant than PEEK (natural).Coefficient of friction in dry running25–100 °C, on X5CrNi18.9 hard-chrome plated, Rz 2 μm, 0,5-5 MPa0,300,25μ dyn.μ stat.Coefficient of friction with oil lubrication25–100 °C, on X5CrNi18.9 hard-chrome plated, Rz 2 μm, 0,5-5 MPa, oil: OL-J46 DIN 515020,30μ dyn.μ stat.0,25Friction coefficient0,200,150,10Friction Coefficient0,200,150,100,050,050,000,00PEEKZX-750V5TZX-750V5KFZX-324/PEEKZX-750V5TZX-750V5KFZEDEX ® basic typesZEDEX ® familiesPost heattreatmentMachiningShippingoverviewSterilizationChemicalresistance19
