PYROLIGNEOUS ACID Resistant O-Rings and Seals
Pyroligneous acid is also known as wood vinegar, wood distillate, pyroligneous liquor, and wood carbon. Pyroligneous acid is a by-product of the destructive distillation of wood, and it is used as a preservative, deodorant, and antiseptic in the food and beverage, animal feed, and agricultural industries.
When rubber is exposed to pyroligneous acid, it can cause cracking, swelling, and loss of strength due to the acid's corrosive properties. Additionally, the acid can cause plasticizers to leach out of the rubber, which can lead to embrittlement and a decrease in the rubber's flexibility.
