Isopropanol, also known as 2-propanol, isopropyl alcohol, or rubbing alcohol, is a colorless and flammable liquid with a strong odor. It is used as a solvent in a variety of industries, including pharmaceuticals, paints, and cosmetics. It is also found in cleaning agents, antifreeze, and windshield washer fluid.
When rubber is exposed to isopropanol, it can cause swelling, cracking, and other forms of degradation. The rubber can become less elastic and lose its flexibility. Over time, exposure to isopropanol can cause the rubber to become brittle and eventually break down. This is especially true when exposed to higher concentrations of isopropanol.
