Traveling out on the door and traveling, it is inevitable to use the trolley case. The trolley case has become a daily necessities in people's lives. People not only pursue the volumetric capacity of the trolley case, but also have different perspectives in terms of aesthetics.
PC: Polycarbonate, Chinese name is polycarbonate.
Polycarbonate (abbreviated as PC) is a polymer having a carbonate group in a molecular chain, and can be classified into aliphatic, aromatic, or aliphatic-aromatic types depending on the structure of the ester group. Among them, the aliphatic and aliphatic-aromatic polycarbonates have low mechanical properties, which limits their application in engineering plastics. Currently only aromatic polycarbonates have been industrially produced. Due to the special structure of polycarbonate, it has become the fastest growing general engineering plastic among the five engineering plastics.
1. High strength and elastic modulus, high impact strength and wide temperature range;
2. High transparency and free dyeability;
3. Low molding shrinkage and good dimensional stability;
4. Good fatigue resistance;
5. Good weather resistance;
6. Excellent electrical characteristics;
7. Tasteless and odorless, harmless to the human body in line with health and safety.
