TCL is used used as a key component in performance polymers and aramid 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. Mixes of terephthaloyl chloride (TCL) and isophthaloyl chloride (ICL) are available on request. DuPont offers TCL as white, free-flowing flakes and as a molten liquid in bulk. TCL is soluble in methylene chloride and other organic solvents.
Specifications and other information for TCL are easily obtained by sending us a request form or by contacting us.
