ARSENIC TRISULFIDE Resistant O-Rings and Seals
Arsenic trioxide, also known as arsenic oxide, arsenic trioxide, and arsenic(III) oxide, is a chemical compound with the formula As2O3. It is the most common form of arsenic and is mainly used in the production of glass, ceramics, paints, and other construction materials. It is also used in some medical applications, such as for treating certain types of cancer.
When rubber is exposed to arsenic trioxide, the rubber can be weakened due to the corrosive nature of the chemical. This can cause the rubber to become brittle, crack, or tear. The rubber can also swell or discolor due to the chemical reaction. In extreme cases, the rubber can become completely destroyed. The rate of degradation depends on the temperature, concentration, and type of rubber 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.
