PC is a light yellow or colorless fully transparent raw material, hard and tough with a high luster.Polycarbonate (commonly abbreviated as PC) is a high polymer material with a molecular chain containing carbonate groups. Depending on the structure of the ester group, it can be divided into various types such as cyclic, aliphatic, and cyclic-aliphatic. Among them, due to the lower physical properties of cyclic and cyclic-aliphatic polycarbonate, its application in rubber products is limited. Currently, only aliphatic polycarbonate has been industrialized. Due to the diversity of the polycarbonate structure, it has become one of the fastest-growing general-purpose rubber products among the five major engineering plastics.
