Trimethylolpropane, also known as trimethylolpropane triacrylate or TMPTA, is a synthetic compound used as an additive in the production of plastics, paints and coatings. Common uses include cross-linking agents, modifiers and plasticizers.
When rubber is exposed to trimethylolpropane, the common types of failures can include swelling, cracking and embrittlement. The rubber can become brittle and unable to withstand the pressure of the application, leading to a failure. Additionally, the rubber can become discolored and brittle due to the corrosive nature of the chemical. The rubber may also experience degradation due to oxidation, reducing its ability to withstand high temperatures.
