SubstitutionexamplesWhich material canreplace the ZX-100K?Bronze / Sintered bronzeup to 60 °C universal replaceable;the strength must betestedTargets: cost reduction,friction and wear reduction,dry running condition,corrosion prevention.PEEKtaking into account thetemperature and the chemicalresistant required, replaceable.Targets: cost reduction,wearreduction, increment of thePV-value.PolyamideTargets: friction and wearreduction, load increment,increment of the resistanceto atmospheric and chemicalcorrosion. Prevention ofstrength decrements andvolume variations through themoisture absorption.POMTargets: friction and wearreduction, load increment,increment of the resistanceto weathering, prevention ofvolume variations throughthe moisture absorption. Itprevents the outgassing of theformaldehyde in case of fire.PE UHMWwith strong abrasive wear notreplaceableTargets: wear reduction, loadincrement, stiffness increment,increment of the operatingtemperature range.Stress / Strain (ISO 527) Flexural E-Modulus (ISO 178)Stress [MPa]p x v value [MPa x m/min]120100806040205040302010000 2 4 6 8 10 12 14 16 18 20 22Strain [%]1 10 100Sliding speed [m/min]ZX-100AZX-100KZX-100MTZX-100EL63POM CPE UHMWPA6PEEKZX-100K is stiffer and stronger than POM, PA oder PE UHMW,similar elongation at break as PEEK.

PEUHMW, PA6 are for applications withdynamic friction less appropriated.Impact resistance notched (ISO179/1eA)PA6PEEKZX-100K loses, up to 90 °C, just a little part of its stiffness. Thestiffness decrement of the plastic materials, during elevatedtemperature, must be taken into consideration.POM CPE UHMWPA6PEEKThe thermal expansion coefficient of the ZX-100K is smallerthan the one of POM, PE UHMW and PA6. Precision applicationsare possible.WearPOM CPE UHMWPA6PEEK-196 -70 23 60 100Temperature [°C]Elastomer modified ZX-100EL63 has got the highest Charpyv-notch test result.
