Tetraethylorthosilicate, also known as TEOS, is a chemical commonly used as a precursor in the production of silicon-based polymers and ceramics. It is often used as a crosslinking agent for polymers and as a coating for metal surfaces. Common industries that use TEOS include the automotive, aviation, and electronics industries.
When rubber is exposed to TEOS, the rubber material can become brittle or break down over time. This is due to the chemical reaction between the TEOS and the rubber, which can lead to cracking, shrinking, and discoloration of the rubber. Additionally, the chemical can cause the rubber to swell and lose its elasticity, making it less effective for use in applications that require flexibility and sealing.
