FC PCA Resistant O-Rings and Seals
FC PCA stands for Fluorinated Carbon Polymer Acids. It is a specialty chemical used in a variety of industries, such as oil and gas, food processing, and agricultural chemicals. It is also known as Fluorinated Carbon Polymer Acid, Fluorinated Carbon Polymer Acid Ester, Fluorinated Carbon Acid, and Fluorocarbon Acid.
Common failures when rubber is exposed to FC PCA include cracking, swelling, and discoloration. These failures can occur 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. It is important to note that the effects of FC PCA on rubber can be mitigated by using more resistant rubber compounds and by utilizing protective coatings.
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.
