TRIMETHYLPENTANE Resistant O-Rings and Seals
Trimethylpentane, also known as isopentane or iso-pentane, is a synthetic compound used as a fuel, solvent and aerosol propellant. It is also used as a refrigerant and aerosol propellant. Common uses include fuel additives, aerosols, solvents, refrigerants and propellants.
When rubber is exposed to trimethylpentane, the common types of failures can include swelling, cracking, discoloration and embrittlement. Swelling can occur due to the solvent properties of the chemical, while cracking can occur due to embrittlement. Discoloration can occur due to the chemical’s corrosive nature, while embrittlement can occur due to oxidation. Additionally, the rubber can become brittle and unable to withstand the pressure of the application, leading to a failure.
