PCT is polybutylene terephthalate 1-4 - dimethyl cyclohexane, the PTA and through a system of CHDM. The polyester for the semi-crystalline thermoplastic resin. Although the PCT rate higher, but still need to choose a suitable catalyst system to improve the response rate, and the ultimate control of viscosity. The entire process to be strictly controlled polymerization of oxygen degradation, and thereby achieve high quality.

PCT most notable features excellent heat resistance, mechanical properties and chemical resistance properties, UV-resistant properties are relatively good, good performance and low processing costs, in many areas of alternative PPS, PBA. In the automotive industry, electronic industry and the pharmaceutical industry has good market prospects.
