Trelleborg Sealing Solutions material 4470 is based upon
medium nitrile elastomer. It therefore exhibits excellent
resistance to mineral oil, mineral and lithium based
greases, kerosene and many other chemicals.
The indicated material properties at measured values are mean values determined with standard test bars. They may not be used as
specification values and they are not directly comparable to material properties of finished parts. This is to emphasise that the customer
himself is obliged to test the material with regard to its suitability in the application. This data sheet has not a change of service.
Die unter Istwert angegebenen Kennwerte sind Mittelwerte und wurden an Normprobekörpern bestimmt. Sie dürfen nicht als
Spezifikationswerte verwendet werden. Auch sind sie nicht mit am Fertigteil bestimmten Kennwerten vergleichbar. Der Abnehmer ist
insbesondere nicht davon befreit, selbst die Eignung unserer Ware für den beabsichtigten Verwendungszweck zu prüfen. Das Datenblatt
unterliegt nicht dem Änderungsdienst.
