PHOSPHOROUS TRICHLTO 158°F ORIDE ACID Resistant O-Rings and Seals
Phosphorous trichloride acid, also known as trichlorophosphonic acid or trichloro- metaphosphoric acid, is a colorless and fuming liquid with a boiling point of 158°F. It is commonly used as a disinfectant, an industrial cleaner, and a reagent for organic synthesis.
When rubber is exposed to phosphorous trichloride acid, it can suffer from swelling, cracking, hardening, discoloration, and accelerated aging. The degree of damage to the rubber depends on the concentration of the chemical, the type of rubber, and the length of exposure. Prolonged exposure can cause complete degradation of the rubber.
