Tritan plastic should be the so-called * * * polyester, abbreviated as PCTG, which is a * * * polyester polymerized from terephthalic acid, tetramethylcyclobutanediol and cyclohexanediol. Eastman, the invention company of this plastic, also applied for a patent in China, with the patent application number of CN200680020545.
This kind of plastic has many advantages. It was invented in 2007, which solved many disadvantages of plastics. It has good toughness, high impact strength, high hydrolysis stability, chemical resistance and high transparency. Moreover, there is no bisphenol A(BPA) in the PC, which can be said to be close to perfection.
However, there is no absolute safety in materials, and the perfection of Tritan is largely due to the fact that many data have not been fully verified. Of course, FDA is a safe evidence, but many substances are found to be harmful after long-term application.
Therefore, it is not yet certain that Tritan is absolutely safe. For example, the antimony catalyst that Tritan may use in the synthesis process is a potential danger. But there is no need to be afraid to use it. On the whole, the safety of plastics is still worthy of recognition, so don't worry.
