TRIFLUOROACETIC ACID Resistant O-Rings and Seals

Trifluoroacetic acid, also known as TFA, is an organic compound used as a solvent in the production of pharmaceuticals and pesticides, as a reagent in organic synthesis, and as a flame retardant. It is also used in some industrial processes, such as etching and cleaning.

When rubber is exposed to TFA, it can become brittle, break down, and become susceptible to deterioration over time. This is due to the acid's ability to dissolve and degrade certain types of rubber, leading to a loss of strength and elasticity. Additionally, TFA can cause rubber to swell, discolor, and become sticky due to the formation of a film-like layer on its surface. The rubber can also become more susceptible to other chemical attack, such as oxidation and hydrolysis.
