DECALIN Resistant O-Rings and Seals
Decalin (also known as DECAHYDRONAPHTHALENE) is an organic compound used primarily as a solvent and intermediate in the production of polymers and polyesters. It is also commonly used in the production of paint and varnish removers, as a rust remover, and as a fuel for motor vehicles.
When rubber is exposed to decalin, the common types of failure are swelling, hardening, cracking, and accelerated aging. Swelling occurs when the rubber absorbs decalin, causing it to expand and become brittle. Hardening occurs when decalin reacts with the rubber, making it harder and less flexible. Cracking occurs when the rubber becomes brittle and breaks apart. Accelerated aging occurs when the decalin causes the rubber to degrade more quickly than usual.
