DENATURED ALCOHOL Resistant O-Rings and Seals
Denatured alcohol, also known as methylated spirits, is a form of ethanol that has been made toxic or otherwise unfit for consumption. Common uses of denatured alcohol include industrial solvents, fuel for marine stoves, fuel for camp stoves, and cleaning agent for glass and windows.
When exposed to denatured alcohol, rubber materials can experience swelling, softening, and hardening. Swelling of the rubber material can occur due to the presence of polar molecules in the alcohol, resulting in an increase in volume and a decrease in tensile strength. Softening of the rubber material can occur due to the leaching of plasticizers, resulting in a decrease in the rubber's hardness and a decrease in its ability to resist abrasion. Hardening of the rubber material can occur due to the presence of oxygenated compounds in the alcohol, which can cause cross-linking of the rubber material and a decrease in elasticity.
