ICL is a difunctional acid chloride used in a variety of performance polymers and fibers, where it is valued for flame resistance, temperature stability, chemical resistance, and flexibility. In addition, it is an effective stabilizer for urethane prepolymers due to its ability to scavenge water.
ICL is a clear water-white liquid above its freezing point and a white crystalline solid at room temperature. Mixes of isophthaloyl chloride (ICL) and terephthaloyl chloride (TCL) are available on request. DuPont offers ICL in cast form in drums and in tank trucks and isotanks as a molten liquid. ICL is soluble in methylene chloride and other organic solvents.
Specifications and other information for ICL are easily obtained by sending us a request form or by contacting us.
