ANIMAL FATS Resistant O-Rings and Seals

Animal fats are lipids derived from animal sources such as beef, pork, and poultry. Common uses of animal fats include cooking, baking, and in the manufacture of soaps, cosmetics, and candles. Animal fats are also used as a source of energy and provide essential fatty acids.

Common types of failures when rubber is exposed to animal fats include swelling, softening, and cracking. Swelling is caused by the animal fats penetrating the rubber and causing it to expand, while softening occurs from the animal fats breaking down the rubber molecules and making them more pliable. Cracking occurs due to the animal fats breaking down the rubber molecules and causing them to become brittle.
