DECANE Resistant O-Rings and Seals
Decalin, also known as Decane, is a hydrocarbon with the chemical formula C10H22. It is a colorless, volatile liquid with a boiling point of 174.2 °C. Decalin is often used as a solvent in the production of perfumes, lacquers, plastics, and rubber. It is also used as a fuel component in jet engines and as a fuel additive in diesel fuel.
When exposed to Decalin, rubber materials can be susceptible to swelling, cracking, hardening, and loss of elasticity. Swelling of the rubber material can occur due to the solvency of the hydrocarbon, resulting in a decrease in tensile strength and an increase in the rubber's propensity to crack. Hardening of the rubber material can occur due to the accelerated oxidation of the rubber due to the presence of the hydrocarbon. Finally, exposure to Decalin can cause rubber to lose its elasticity, resulting in a decrease in the material's ability to return to its original shape.
