When choosing a water bottle, the material it is made from is crucial for health and safety. Among the popular plastic materials are Polycarbonate (PC), Tritan, and Polyphenylsulfone (PPSU). Each of these materials has distinct characteristics and safety profiles.
1,Polycarbonate (PC) is known for its strength and transparency, but it has a significant drawback: it can release Bisphenol A (BPA) when exposed to high temperatures. BPA is harmful to human health, impacting the nervous and reproductive systems, as well as development in animals. Many manufacturers often combine materials, using PP (Polypropylene) for the lid and PC for the body. It is essential to note that PC cups should only hold cold water; when filled with hot liquids, they can leach harmful substances.
2,Tritan is a copolyester that withstands heat between 94°C and 109°C. It is frequently used to manufacture baby products and water cups due to its moderate price and good performance. However, exposure to excessively high temperatures can lead to deformation or cracking, so it's important to avoid overheating.
3,PPSU boasts impressive heat resistance, withstanding temperatures up to 200°C. It is capable of enduring repeated steam sterilization, making it ideal for baby bottles, utensils, and water cups. PPSU is easily identifiable by its amber color and is typically priced higher due to its superior qualities.
When selecting a water cup, ensure it bears one of the following labels: PP, 7-Tritan, or 7-PPSU. These materials are safe for drinking water. The ranking of these materials in terms of quality is as follows: PPSU > Tritan > PP.
Avoid cups without markings on the bottom or body, as they are often of questionable quality. Additionally, consider factors such as sealing capability and ease of cleaning. At Aohea, we guarantee the quality of our water cups, ensuring a safe and reliable choice for hydration.
