What are the main ingredients of PET? What's the difference between PET resin and PET?.
PET has ester bond. It can decompose under strong acid, alkali and water vapor. It has good resistance to organic solvents and good weather resistance. The disadvantage is the slow crystallization rate, difficult molding, high molding temperature, long production cycle and poor impact. In general, the processing and physical properties are improved by strengthening, filling and blending. The effect of glass fiber reinforcement is obvious, and the rigidity, heat resistance, drug resistance, electrical property and weather resistance of resin are improved. However, it is still necessary to improve the disadvantage of slow crystallization rate, and some methods such as adding nucleating agent and crystallization promoter can be adopted. Flame retardant and flame retardant dropping agent can improve flame retardancy and self extinguishing of PET. To improve PET performance, PET can form alloys with PC, elastomers, PBT, PS classes, ABS, and PA.
Has excellent physical and mechanical properties in a wide temperature range, long-term use temperature is 120 degrees centigrade, excellent electrical insulation, even under high temperature and high frequency, the electric performance is still good, but poor corona resistance, creep resistance, fatigue resistance, wear resistance, good dimensional stability.
PET polyethylene terephthalate (PET) English Name: polyethylene terephthalate (PET), widely used as fiber and engineering plastic resin can be divided into non engineering plastics and engineering plastics in two categories, non engineering plastic grade is mainly used for bottle, film, sheet, baking food containers etc..
