What is the material of tritan? Tritan is a safe and environmentally friendly plastic raw material. It has passed the FDA certification of the US Food and Drug Administration and the designated materials for baby products in Europe and America. Let's see what material tritan is made of.
What is the material of tritan 1 I. tritan?
The new generation of polyester plastic products developed by 1. Company are not only building materials, but also products widely used in people's lives. They can be made into all kinds of articles, which brings convenience to our life. Through the company's continuous research and development, we will produce high-quality products, which will make people feel more at ease when using them in their lives.
Secondly, the advantages of Tritan are introduced.
1, the material selection is quite strict and does not contain BPA. Tritan does not contain BPA in the polymerization process, and will not release BPA in the use process, which meets the requirements of environmental protection and FDA.
2. As far as the material of the product is concerned, the clear and transparent transmittance is >; 90%, smog
3. Excellent impact strength is relatively strong and durable, and the notched impact strength is between 650 and 980 J/m depending on the brand, which is equivalent to the impact strength of PC.
4. During use, * has chemical resistance and hydrolysis resistance. Tritan can resist the corrosion of detergents, detergents, hydrocarbon solvents, oils, perfumes, etc. It can resist hydrolysis in hot and humid environment.
5. It is characterized in that the high and low pressure thermal deformation temperature (HDT @ 0.455MPa) is between 94℃- 109℃ according to different brands.
6. The test conditions of good fluidity are 2. 16kgf pressure and 280℃ melt temperature. According to different brands, the melt index (MI) is between 15.3-29.5.
7. In the manufacturing process, Tritan brand which is easy to form and process can be processed by various methods, such as injection, extrusion, extrusion (EBM), injection-stretching and blow molding (ISBM). Generally speaking, the mold that PC can produce normally, Tritan can produce without modification, and the production cycle time is very close.
What is the material of tritan? 2 shortcomings of triptan.
Tritan has obvious shortcomings. Boiled in water, sterilized at high temperature will deform. Generally, the maximum temperature resistance is 94 degrees. Above this temperature, no harmful substances will be produced, but it may be deformed and cracked.
If you have the habit of boiling and disinfecting plastic cups at high temperature, it is recommended to buy food-grade PC and PP materials without BPA, which are resistant to high temperature and safe.
Tritan, what material?
It is a safe and environment-friendly plastic raw material. It has passed the FDA certification of the US Food and Drug Administration and the designated materials for baby products in Europe and America.
Tritan has many advantages, such as no BPA, good transparency, strong impact strength, chemical resistance, hydrolysis resistance, high temperature resistance, good fluidity and easy processing. It has a wide range of applications, such as household goods, small household appliances, baby products, medical care, cosmetics, outdoor and other fields.
Is tritan made of good material?
According to the analysis of patent U.S. Pat.No. US8623483, tritan plastic should be a so-called * * * polyester, abbreviated as PCTG, which is a * * * polyester polymerized from terephthalic acid, tetramethylcyclobutanediol and cyclohexanediol. Eastman, the inventor of this plastic, also applied for a patent in China with the patent application number 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 a large number of data have not been fully verified. Of course, FDA is the evidence of safety, but many substances are found to be harmful after long-term use, so it is not yet possible to assert that triptan is absolutely safe. For example, the antimony catalyst that Tritan may use in the synthesis process is a potential danger. But don't be afraid to use it. Generally speaking, the safety of plastics is still worthy of recognition, so don't worry.
How long can tritan live?
Generally speaking, if the water cup can be used for about half a year, it would be better to change it. If you buy some big brands, it will take a long time, and then you should pay attention to frequent disinfection in water.
The light transmittance is above 90%, which looks like crystal luster. In addition, the water cup made of this material also has good scratch resistance and hydrolysis resistance, but the plastic cup has a certain service life, so it is recommended to replace it once every six months or one year.
What is the material of tritan? 3 Triptan material should not be overheated, otherwise it will be harmful to human body. Tritan is a kind of material called triphenylmethane polyester, which is a new generation of polyester material introduced by Eastman Company in the United States.
Tritan*** polyester is a transparent, tough and BPA-free material. Compared with others, Tritan*** polyester has better impact resistance, heat resistance and dishwasher cleaning tolerance. In addition, Tritan*** polyester also has the characteristics of deodorization, deodorization and pollution resistance, and has high chemical stability and food safety.
Because it is also relatively new material, I don't know much about it. It seems that the temperature resistance is not as good as that of PC, only 99~ 109C, but it is still satisfactory for hot water and has FDA certification.
superiority
1). No bisphenol A..
Tritan does not contain BPA in the polymerization process, and will not release BPA in the use process, which meets the requirements of environmental protection and FDA.
2). Clear and transparent
Light transmittance > 90%, haze
3). Excellent impact strength
The notched impact strength is 650-980J/m depending on the brand, which is equivalent to the impact strength of PC.
4) Excellent chemical resistance and hydrolysis resistance.
Tritan can resist the corrosion of detergents, detergents, hydrocarbon solvents, oils, perfumes, etc. It can resist hydrolysis in hot and humid environment.
5). High temperature resistance
The low-pressure thermal deformation temperature (HDT @ 0.455MPa) is between 94℃ and 109℃ according to different brands.
6). Good liquidity
The test conditions are 2. 16kgf pressure, 280℃ melting temperature, and the melting index (MI) is between 15.3-29.5 according to different brands.
7). Easy to form and process.
Tritan brand can be processed by various methods, such as injection, extrusion, extrusion blow molding (EBM), injection stretch blow molding (ISBM) and so on.
8). Easy for secondary processing.
The secondary processing methods that Tritan can apply are: UV adhesive bonding, ultrasonic welding, surface printing and painting, surface vacuum coating, etc.
9) The residual stress of the product is small.
After injection molding, the residual stress of the product is smaller than that of PC, and no subsequent annealing treatment is needed. Tritan's products are more durable because there is less chance of residual stress cracking during use.
