Urea, also known as carbamide, is a chemical compound that is commonly used as a fertilizer and animal feed supplement. It is also used in certain industrial processes as a source of nitrogen and as a stabilizer.
When exposed to urea, rubber materials can become hardened and brittle over time, leading to cracks and other failures. This is due to the fact that urea is highly hygroscopic, meaning it absorbs moisture from the environment which can lead to accelerated aging of the rubber materials. Additionally, certain rubber materials can become chemically degraded when exposed to urea, causing them to become brittle and eventually fail.
