Elastomer Seals

Le Guarnizioni Elastomeriche si differenziano da quellle in ptfe per una serie di caratteristiche intrinseche dei materiali; infatti gli elastomeri presentano un modulo sensibilmente inferiore a quello del ptfe, il che ne rende più facile l'assemblaggio in cava chiusa. Al basso modulo si associa, almeno per il Poliuretano, una maggiore resistenza all'abrasione che ne permette l'impiego su superfici che non sarebbero idonee per il ptfe (questo non vuole essere un invito a realizzare superfici mal finite !!). Ai vantaggi si affiancano anche alcuni svantaggi come il maggiore coefficiente d'attrito che limita le velocità di scorrimento, e la relativamente modesta resistenza alla temperatura (FKM escluso). Bisogna anche considerare che gli elastomeri hanno una compatibiltà ristretta agli oli ed ai prodotti chimici in generale, mentre il ptfe ha una resistenza chimica quasi universale.

The technical-application data specified in catalogues, documentation and on this website are the result of more than forty years of experience and laboratory tests. The seal types suggested are the result of laboratory tests and thousands of field tests; however, the working conditions foreseen may not coincide with those of new applications and so lead to unexpected results. Therefore, HD Slippers Srl shall not be held responsible for the failure of sealing components that have not been tested under the actual working conditions. For new applications and the consequent manufacturing of specific seals, the user must conduct tests under the actual working conditions in order to approve the validity of the chosen solution. HD Slippers Srl guarantees the repeatability of the characteristics of seals tested and approved, except for subsequent modifications of applications and/or equipment and/or its components and/or processes, by the customer or a third part.
