FERMENTATION GAS Resistant O-Rings and Seals
Fermentation gas, also known as carbon dioxide (CO2), is a colorless, odorless gas that is produced as a by-product of the fermentation process. It is widely used in the food and beverage industry, as well as in many industrial processes, such as carbonation of soft drinks and beer, and in the production of fertilizers, plastics, and polymers.
When rubber is exposed to CO2, it can lead to oxidation and cracking. Oxidation occurs when the CO2 reacts with the rubber’s surface, leading to a decrease in the material’s tensile strength and an increase in its brittleness. This can lead to cracking and eventually failure of the rubber material. Additionally, CO2 can cause swelling and softening of the rubber, which can also lead to cracks and eventual failure. For this reason, it is important to use rubber materials that are resistant to the effects of CO2, such as EPDM, butyl rubber, and fluorosilicone.
