 fibers, where it imparts flame resistance, chemical resistance, temperature stability, light weight, and very high strength. TCL is also an effective water scavenger, used to stabilize isocyanates and urethane prepolymers.

TCL is a clear, water-white liquid above its freezing point and a white crystalline solid at room temperature, soluble in organic solvents. Its melting point is 81.5-83 °C, its boiling point is 265 °C. It is corrosive.
