What are the materials of tritan and ppsu?

Tritan material is good. The main raw materials of triptan include dimethyl terephthalate, 1, 4- cyclohexanedimethanol and 2.2.4.4- tetramethyl-1.3- cyclobutanediol. Tritan is made of improved pct, which has excellent light transmittance, impact resistance and weather resistance, and there is no restriction on the types of foods that come into contact with it. The working temperature is lower than or equal to 100 degrees Celsius. According to the analysis of patent U.S. Pat.No. us8623483, tritan is a polyester, which is a polymer of dicarboxylic acid, tetramethylcyclobutanediol and cyclic ethylene glycol. The company that invented it is Eastman. This material has many advantages, which solves the shortcomings of many plastic products, such as good toughness, high impact strength, high hydrolysis stability and high stability.
