What is the difference between PS material and AS material for plastic water cups?

In the previous articles of the editor, I have explained the difference between the plastic materials of plastic water cups, but the detailed comparison of PS and AS materials does not seem to have been explained in detail. Taking advantage of the opportunity of a project that Xiaobian came into contact with recently, Xiaobian shared the difference between PS material and AS material for plastic water cups.

Before sharing, I would like to tell you my personal thoughts on creating mug articles over the years. I started writing mug articles in 2020, from the humble writing to now can be more comprehensive and more scientific analysis for friends. These years in the writing of articles in the editor benefit a lot, but, creation is also boring and monotonous. From the beginning of the pain of not being able to write more understandable and richer articles to the pain of not being able to create one article a day like in the early days.

The number of friends who pay attention to me is gradually increasing, and some articles are naturally pushed to flow due to the high quality of creation.But there are still more articles that are not recommended. I sincerely hope that friends who like the articles shared by the editor and bring help through the articles will pay attention to the editor and help the editor to share the articles you think are valuable so that more friends can see them. Here I also hope that due to the depletion of creative material to mention one more about the water cup kettle type of problem and material, I thank you for your support.

In the previous article, I mentioned that the current market plastic cups are generally used in which materials, such as Tritan, PP, PPSU, PC, AS, etc.. PS as a common material for plastic cups or rarely mentioned, is also in contact with a European customer's procurement needs, I was able to contact the PS material. Many foreign trade friends know that the entire European market, for example, Germany is implementing plastic restrictions, the reason is that plastic materials are not easy to decompose not easy to recycle and many plastic materials contain bisphenol A, made into mugs will cause harm to the human body after use. For example, PC material, although in some performance is stronger than AS and PS, but because it contains Bisphenol A is banned in the European market for mug production.

PS, commonly known as a thermoplastic resin, colorless and transparent, high translucency. In contrast to these plastic materials mentioned earlier, the low cost of materials is its advantage, but PS fragile toughness, and this material contains Bisphenol A. PS material made of water cups can not be filled with high temperature hot water, otherwise it will release Bisphenol A harmful substances.

AS, acrylonitrile-styrene resin, polymer material, colorless and transparent, high translucency. Compare with PS more resistant to fall, but not durable, especially not resistant to temperature difference. After loading hot water and quickly loading cold water, the surface of the material will appear obvious chafing, placed in the refrigerator freezing the same will appear chafing. Although hot water will cause the cup to crack, but will not release harmful substances, so can pass the EU test. Material cost is higher than PS.

How can you tell from the finished product that the mug is made of PS or AS material. By looking at these two materials, we can see that the colorless transparent mug will naturally show a blue effect. But if you want to tell whether it is PS or AS, you need to use professional testing equipment.
