Long-term up to 300 °C ZX-750 familyBasic type ZX-750V5TCharacteristics– hard, stiff, tough– high dimensional stability– high fatigue strength– high weathering resistance– good fire behavior (lowgeneration of flue gases)– resistence to stress cracking– vacuum suitable– good machinability– bondable and weldable– contains PTFEZX-750V5TChemicalresistanceV-valueCostWearTemperatureStrengthrecisionmpactresistanceFrictionResistanceUV-radiation(1000 hours Xenon DIN 53597)tensile strength: no alterationelongation at break: –30 %Gamma-radiationlimit absorbed dose 8000 kGyChemicals, resistancesolvent, dilute acids and alkalisChemicals, unstablestrong acids and alkalis, oxidizingagentsLubricants and fuelsresistantWatermax. water absorption: 0,7 %dimensional changes: 0,4 %up to 120 °C resistantFire behavioroxygen index (LOI): 52 %classification: V-0 (UL94)Operationalparameters*Temperature (T)–250 °C to +300 °C (+320 °C)surface pressure (p)max. 41 (125) MPaSliding speed (v)max. 350 m /minFatigue (S)tensile creep strength at 20 °Cand 10 6 stress cycle,1 Hz = 35 MPaAvailable as:– plastic granules– rods– tubes– sheets– machined parts– plain bearings bushes accordingto DINExamples ofusageFriction bearings, madeof ZX-750V5T, meet theextreme requirements of theartificial knee joints. Thanksto a high surface pressureand high wear resistance, amax. backlash of 0,05 mmwill not be exceeded.Modified ZX-750ZX-750V5KFChemicalresistanceV-valueCostWearTemperatureStrengthrecisionmpactresistanceFrictionfibre reinforcedhigh stiffness up to 250 °C, highelongation at break and yieldstress values, low thermal elongation,impact resistant down to–196 °C.T: –250 °C to +280 °C (+320 °C)p: max. 41 (125) MPav: max. 350 m /minS = 55 MPaThis segmental bushing,made of ZX-750V5T(Ø 700 mm), guides andleads into water the floatingweight of 28 t in a deep-seahammer. This extreme stresssubjected part operates inunlubricated conditions, witha 50 Hz impact frequencyand a drop height of 1 m.The existing sliding guideof a chipboard press, isconverted from a greaselubrication condition to a dryrunning condition. Thanks tothe extreme high PV-valueand the high wear resistanceof the ZX-750V5T, the chipboardpress now works just indry running conditions.*Values in the brackets, are valid for shot-term service18 ZEDEX ® basic types ZEDEX ® families Post heattreatmentMachiningShippingoverviewSterilizationChemicalresistance
