THE ENDLESS POSSIBILITIES OF RUBBER
Viton Extreme from DuPont
|The Rubber:||Recently introduced to the market by DuPont.|
|Resistance and properties:|
DuPont has produced a variation on the basis of Aflas, officially also designated FEPM in accordance with ASTM D1418. This is a revolutionary Advance Polymer Architecture (APA) polymer bisphenol vulcanized TFE/Propylene, with a fluorine content of 67%. As a result of its structure, Viton Extreme from DuPont combines the best of FEPM and Special FKM.
There are ETP and TBR versions.
Viton Extreme ETP has the following important properties and probably combines the best of FEPM and Special FKM:
It is resistant to acids, hydrocarbons, low molecular weight esters, ketones and aldehydes, strongly caustic solutions, amines and hot water. Resistance to cold Tg10 is 10 deg C. Note this is not TR 10.
Viton Extreme TBR has the following important properties:
It is resistant to caustics and amines, hydrocarbon oils, acids and steam. It has superior compression set values, lower swelling percentages in the case of long-life seals, and high abrasion resistance.
As a result of its chemical structure, Viton Extreme TBR, like all TFE/Propylene products, is not recommended for fuel seals in the automotive or aviation industries.
|Applications:||Frequently used in the chemical and oil industries.|
