JPX Resistant O-Rings and Seals
JPX, also known as N-Methyl-2-pyrrolidone, is a colorless liquid with a pleasant odor. It is commonly used as a solvent in the rubber and plastic industries, as well as in the printing and dyeing industries. It is also used in the production of agricultural chemicals, pharmaceuticals, and other chemical products.
When rubber is exposed to JPX, it can suffer from a variety of different failures. These can include swelling, cracking, discoloration, and accelerated aging. The degree of failure will depend on the type of rubber, the concentration of the chemical, and the length of exposure. Certain types of rubber, such as natural rubber and silicone, are more susceptible to damage from JPX than others. Additionally, prolonged exposure can cause plasticizers to leach out of the rubber, resulting in embrittlement and cracking.
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.
