Tricresyl phosphate (TCP) is a colorless liquid organic compound also known as tricresyl phosphate, triphenyl phosphate, and trityl phosphate. It is a commonly used industrial chemical in paints, lubricants, and plasticizers. It is also used in the manufacture of aircraft engines, as a flame retardant, and as a solvent for nitrocellulose, waxes, and resins.
In rubber applications, TCP has been known to cause swelling, softening, and cracking due to the presence of aggressive hydrolysis and oxidation components. The chemicals in TCP can react with rubber polymers, causing them to swell and weaken, leading to eventual failure. Additionally, TCP can cause brittleness in rubber due to its low-temperature plasticizing effect, leading to cracking and splitting of the rubber.
