Raw materials for plastic candle cups
Polycarbonate is a kind of colorless, transparent and non-qualitative thermoplastic material. It is a kind of strong thermoplastic resin.
Polycarbonate (PC) is a sub-molecular polymer containing carbonate group outside the molecular chain. According to the layout of the ester group, it is divided into aliphatic group, aromatic group, aliphatic group - aromatic group and other types.In addition, the low mechanical properties of aliphatic and aliphatic - aromatic polycarbonate limit their application in engineering plastics.Only aromatic polycarbonate is available for industrial consumption.Because of the particularity of polycarbonate layout, it has not become the fastest growing general engineering plastics outside the five major engineering plastics.
PC is non-crystalline thermoplastic, high quality heat resistance, good transparency and high impact strength and other physical and mechanical properties.
So plastic candle cups made of polycarbonate have the following advantages：
1. Better flame retardant performance
2. Low shrinkage and good dimensional stability after forming.
3. Be more transparent
3. Health standards that are not harmful to human health
4. Better wear resistance and oxidation resistance
