Application
Since the early days of household goods and the application of small household appliances, more fields have been developed around 2014, including applications such as baby products, medical, cosmetics, outdoor, and some applications are under development.
Safety
Tritan is approved by the Food and Drug Administration (FCN) No. 729 for the design of materials for baby products in Europe and America.
According to the National Standard of the People’s Republic of China GB-4806.6–2016, which was implemented on April 19, 2017, it was approved as a plastic resin for food contact, dimethyl terephthalate and 1,4-cyclohexanedimethanol. Polymer of 2,2,4,4-tetramethyl-1,3cyclobutanediol, approved for use in environments up to 100℃.
Advantage
1). BPA free
Tritan has no BPA in the polymerization process and does not release BPA during use, meeting environmental requirements and the FDA.
2). Clear and transparent
Light transmittance >90%, haze <1%, crystal-like luster.
3). Excellent impact strength
There is no gap impact, and the notched impact strength is between 650-980J/m due to the grade, which is comparable to the impact strength of PC.
4). Excellent resistance to hydrolysis and hydrolysis
Tritan is resistant to corrosion by detergents, detergents, hydrocarbon solvents, oils, perfumes, etc.; it is resistant to hydrolysis in hot, humid environments.
5). High temperature resistance
The low pressure heat distortion temperature (HDT @ 0.455MPa) is between 94 °C and 109 °C depending on the grade.
6). Good mobility
The test conditions are 2.16 kgf pressure and 280 ° C melt temperature. The melt index (MI) is between 15.3 and 29.5 depending on the grade.
7). Easy molding processing
Tritan’s grades can be processed by various methods such as injection molding, extrusion, extrusion (EBM),and injection blow molding (ISBM). In general, molds that can be produced normally using PCs can be produced with Tritan? without modification, and the production cycle times are very close.
8). Easy secondary processing
The secondary processing methods that Tritan can be applied to include: UV glue bonding, ultrasonic welding, surface printing, surface vacuum plating, etc.
9). Small residual stress of the product
After injection molding, the residual stress of the product is smaller than that of PC, and no subsequent annealing is required. Tritan manufactures products that are more durable due to less chance of cracking due to residual stress during use.
