FC TA Resistant O-Rings and Seals
FC TA stands for Fluorocarbon Telomer Acids. It is a specialty chemical used primarily in the oil and gas industry as well as in the food processing and agricultural chemical industries. It is also known as Fluorinated Carbon Telomer Acid, Fluorinated Carbon Telomer Acid Ester, Fluorinated Carbon Polymer Acid, and Fluorocarbon Acid.
Common failures when rubber is exposed to FC TA include cracking, swelling, and discoloration. This is due to the acid's high solubility in water, as well as its corrosive nature. The acid can also react with rubber compounds to weaken the material, leading to further cracking and swelling. To mitigate these effects, more resistant rubber compounds and protective coatings should be used.
Buna-N (NBR, Nitrile, Buna)
Buna-N o-rings also referred to as NBR o-rings and Nitrile o-rings are the most widely used o-ring material in the word because of low cost, good mechanical performance with resistance to water, most basic oils, lubricants and some fuels, many pneumatic, hydraulic systems, and the default choice for basic applications. Buna-N o-rings are not recommended for exposure to sunlight, UV light, ozone and general outdoor weathering or hash chemicals, acids, keytones and many others.
