PPSU feeding bottle

　　PPSU is polyphenylene sulfone, which is a transparent thermoplastic. PPSU products are resistant to high temperatures, including repeated high-temperature steam sterilization.

　　(1) Advantages: light in texture, very resistant to falling and high temperature (180°C). It can be heated by microwave, even if the disinfectant is cooked at high temperature, there is no problem, and no harmful substance bisphenol A will be produced.

　　Even if it undergoes heating water or even high-temperature steam sterilization, it will not release toxic substances, and there is no carcinogen (bisphenol A) that will affect the endocrine. It can withstand up to 180 degrees Celsius and can be heated directly in a microwave oven.

　　(2) Disadvantages: It is easy to have milk scale residues that are difficult to clean, and the hardness is small and easy to wear.

　　The residual milk scale is not easy to clean thoroughly, and the hardness is small and easy to wear.

　　TIPS: What is the best material for plastic milk bottles?

　　At present, the plastic milk bottles on the market are mainly made of PP, PPSU and PES.

　　Heat resistance: PP < PES < PPSU

　　Corrosion resistance: PP < PES < PPSU

　　Transparency: PP < PPSU < PES

　　Cleanliness: PP < PPSU = PES

　　In general, the best is the plastic milk bottle made of PPSU, which ranks first in all aspects, but the plastic milk bottle of this material is the most expensive, and there are fewer products to choose from. The second place is PES material, which is also more expensive. The second is PP material. This plastic milk bottle is not as good as the first two in terms of material, but its performance is also good, and the price is cheap. There are many brands and types to choose from, which is suitable for most families.
