ISOPENTANE Resistant O-Rings and Seals
Isooctane, also known as 2,2,4-trimethylpentane, is a highly flammable hydrocarbon fuel used in a wide range of applications. It is commonly used as a fuel in gasoline and jet fuel, as a solvent in paints, as an aerosol propellant, and as a blowing agent in the production of plastics.
When rubber is exposed to isooctane, it can cause swelling and soften due to the hydrocarbon components. It can also lead to the breakdown of the rubber structure, resulting in cracking, shrinkage, and brittleness. Exposure to isooctane can also cause the rubber to become brittle and harden. The rubber may also become discolored, and the surface can become rough and pitted.
