The long-term service temperature can reach 120 ℃, the electric insulation property is excellent, and even under high temperature and high frequency, the electric property is still good, and the creep resistance, the fatigue resistance, the friction resistance and the dimensional stability are good.
With the continuous development of the application, people put higher and more specific requirements on the polyethylene terephthalate, such as the requirement of antibacterial and mildewproof properties. This is because the plastics are likely to produce mold due to migration of the internal additives or external contamination, which affects the use of the product. In addition, in order to improve the impact resistance of the polyethylene glycol terephthalate, a toughening agent is generally added, and small molecular substances and monomers contained in the conventional toughening agent are a nutrient source of mould, so that the growth of the mould is promoted, and the consumption of an antibacterial agent in a mould-proof material is increased.
At present, the aim is generally achieved by adding antibacterial agents, wherein natural antibacterial agents have high safety but poor heat resistance and are easy to carbonize and decompose; the organic antibacterial agent has the defects of quick and high-efficiency sterilization, but poor long-acting property; the inorganic antibacterial agent has good long-term sterilization effect, but has slow antibacterial effect, and the silver and copper antibacterial agents have the problem of easy color change.
