Pentaerythritol, also known as penta or PEE, is a synthetic chemical used in a variety of industrial applications, such as paint and coatings, explosives, and as an ingredient in certain types of plastics and rubber.
When rubber is exposed to pentaerythritol, it can cause the rubber to become weak and brittle, leading to cracking and tearing. Additionally, the rubber can become discolored and may swell, leading to a potential change in shape. Over time, exposure to pentaerythritol can also cause accelerated aging, which can lead to potential failure.
