PHOSPHOROUS TRICHLORIDE Resistant O-Rings and Seals

Phosphorous trichloride, also known as phosphoryl trichloride, is a colorless and fuming liquid composed of phosphorus and chlorine. It is commonly used as an intermediate in the production of pharmaceuticals, pesticides, and rubber chemicals.

When rubber is exposed to phosphorous trichloride, it can cause a variety of problems, including swelling, cracking, hardening, and discoloration. The degree of damage to the rubber depends on the concentration of the chemical, the type of rubber, and the length of exposure. High concentrations of the chemical can cause accelerated aging and loss of elasticity, while prolonged exposure can cause complete degradation of the rubber.
