Arsenic trichloride, also known as arsenic(III) chloride, is a common chemical used in many industrial applications. It is used in the production of pesticides, herbicides, and fertilizers, as well as in the production of metal alloys and semiconductors. Arsenic trichloride is also used in the production of pharmaceuticals and in the manufacture of rubber products.
When rubber is exposed to arsenic trichloride, there are several common types of failure that can occur. These include a decrease in physical properties such as tensile strength and elasticity, Hardening, cracking, swelling, and discoloration. In addition, the rubber can become brittle and can begin to degrade over time due to the presence of the acid.
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.
