After CBT is melted, catalysts are added to CBT to polymerize it during processing back into PBT, which is the ultimate form used in the molded part.
This low-viscosity intermediate-step CBT creates an engineering thermoplastic--PBT--that can be used in processes designed for thermoset resins. For example, melted CBT can flow like a thermoset into the glass- or carbon-fiber reinforcing material in composites, but the finished product retains the thermoformability and other properties of a thermoplastic
