Argon gas is a colorless and odorless gas that is the most common in the Earth's atmosphere. It is used in welding, lasers, and lighting applications, as well as for inert atmospheres, as a refrigerant, and as an anesthetic in medical settings.
When rubber is exposed to argon gas, it can cause a variety of failures. Low temperatures can cause embrittlement, cracking and hardening of the rubber. Also, rubber can become brittle and break down due to oxidation. In some cases, argon gas can react with certain rubber compounds and cause them to swell or soften. The reaction can also cause the rubber to degrade and become porous. As a result, it is important to select the right type of rubber compounds when exposed to argon gas.
