Methane, also known as marsh gas or methane gas, is a colorless, odorless, flammable gas that is the primary component of natural gas. It is widely used in the production of fuel, fertilizer, and plastics, as well as in the production of synthetic rubber.
When rubber is exposed to methane, it can cause a number of issues, including softening, swelling, cracking, and discoloration. Additionally, prolonged exposure to methane can cause rubber to become brittle, leading to a decrease in strength and elasticity. The presence of air or water vapor can also accelerate the degradation of rubber when exposed to this chemical. In some cases, the rubber can become so brittle that it is no longer usable.
