Oleic Acid (also known as cis-9-octadecenoic acid) is a monounsaturated fatty acid found in various animal and vegetable fats. It is commonly used in the production of soaps, detergents, cosmetics, pharmaceuticals, and foods.
When exposed to oleic acid, rubber can experience swelling, leading to a decrease in physical properties such as tensile strength and elongation. Additionally, oleic acid can cause the rubber to become brittle and crack, resulting in material failure. Additionally, oleic acid can cause rubber to become discolored or stained, leading to aesthetic issues.
HNBR, or hydrogenated NBR, is created by modifying the properties of NBR to increase the materials resistance to ozone, many chemicals, heat, aging, and abrasion. Like NBR, HNBR still holds onto its resistance to oils and fuels.
