What is Viton Extreme?
Viton® ETP belongs to a range of materials known within the Viton range as made with APA (Advanced Polymer Architecture). It is commonly known as Viton® ETP, or its APA name of Viton ETP-600S
Though we have a separate feature on APA (see Q & A's Viton APA) as a whole material group, this particular grade is worthy of a special section to itself as it has outstanding resistance to a wide variety of extremely aggressive media across many markets such as Offshore, Industrial and Automotive.
What are the main differences between Viton Extreme and other Viton grades?
Even the best materials have their weaknesses. Chemicals with a high pH value (eg. Ammonia & Sodium based solutions) can attack the traditional vinylidene fluoride (VF2) containing elastomers, causing premature seal degradation. Viton® Extreme ETP combines the excellent thermal resistance of Viton® with its unique resistance to chemicals that exceed the capabilities of conventional fluoroelastomers. Its' low swell in hydrocarbons ensures exceptional service in automotive and oil field applications.Also applications can be considered in the pharmaceutical Industry where fluids of a highly caustic nature can be encountered.
Is Viton ETP expensive?
It is much more expensive than the conventional fluoroelastomers, but its extreme base resistance enables downtime to be considerably reduced, which saves money.
What are the temperature limits of Viton Extreme ?
As with all Viton elastomers the general upper limit is around 200 deg C but this can be impacted by a number of factors determined by the specific application. As determined by the TR-10 value the lower temperature range is not as low as some of the other Viton grades, such as GLT & GFLT but this grade is able to withstand a wider range of aggressive chemicals than other grades.
