The healthy material is not resistant to high temperatures, and its low pressure heat distortion temperature (HDT @ 0.455MPa) is between 94°C and 109°C depending on the brand. That is to say, under normal circumstances, the maximum temperature resistance is 94 degrees, and it will not work beyond this temperature. Although no harmful substances will be produced, deformation and cracking may occur.
The full name of tritan is Tritan Copolyester, a new generation of copolyester developed by Eastman. It has passed the FDA certification of the US Food and Drug Administration, and has become the designated material for infant products in Europe and the United States.
In the past, most of the materials used in the manufacture of infant products have always been PC materials. Later, it was discovered that BPA (bisphenol-A) would be produced after PC hydrolysis.
Modern medical research believes that bisphenol A exceeding a certain dose may affect human health (including animals). For example, long-term intake of trace amounts of BPA will cause confusion in the endocrine system, which is likely to have an adverse effect on the reproductive system and disrupt the balance of sex ratio. , So some countries and regions have restricted or disabled PCs.
Manufacturers are facing environmental pressure and are looking for materials that can replace PC. Tritan has emerged in this market context.
In addition to the application of infant products, household products and small home appliances, tritan has developed into more fields around 2014, including applications such as baby products, medical care, cosmetics, and outdoor applications. Other applications are under development.
