BUTYNE DIOL Resistant O-Rings and Seals

Butylene glycol, also known as butyne diol, is a colorless, odorless liquid with a wide range of industrial and commercial uses. It is used as a solvent, wetting agent and in the manufacturing of plastics, rubber, printing inks, pharmaceuticals, and other products. Common uses for butylene glycol include plasticizers, antifreeze, and as a reactive intermediate.

When rubber is exposed to butylene glycol, it can cause the rubber to become brittle, crack, discolor, swell, or shrink. The rubber can also become brittle and crack due to exposure to high temperatures and oxygen. In addition, exposure to UV light can cause the rubber to fade, crack and discolor. The rubber may also become sticky if exposed to high concentrations of butylene glycol.


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.
