Cumaldehyde, also known as 4-methylbenzaldehyde, is a volatile organic compound commonly used in perfumes and as a flavoring agent. It is also used in the production of plasticizers and in some rubber products.
When rubber is exposed to cumaldehyde, it can cause the rubber to become brittle, leading to cracking and failure of the rubber part. The chemical can also cause discoloration of the rubber, leading to surface defects. Additionally, the exposure of cumaldehyde can lead to embrittlement of the rubber, causing it to become harder and less flexible.
