TRIETHYL PHOSPHATE Resistant O-Rings and Seals
Triethyl phosphate, also known as TEP, is an organophosphate compound used in a variety of industrial applications. It is used as a solvent in paints, coatings, and inks, as well as a flame retardant in plastics and textiles. It is also used as an intermediate in the production of other chemicals, as a fuel additive, and in the manufacture of pharmaceuticals.
When rubber is exposed to TEP, the material can become brittle and cracked due to swelling and chemical attack. Additionally, TEP can cause the rubber to become discolored and sticky due to the formation of a film-like layer on its surface. Over time, the rubber can harden due to the loss of plasticizer and become susceptible to cracking and tearing.
