PPSU baby bottles are feeding utensils for infants and toddlers crafted from polyphenylsulfone (PPSU). Characterized by a faint golden-yellow tint, they are BPA-free and exhibit high heat resistance, withstanding temperatures up to 180°C. Capable of enduring repeated high-temperature sterilization, these bottles combine the safety attributes of glass bottles with the shatter resistance of PC materials. In terms of design, the products are categorized by neck diameter into standard-neck and wide-neck types; available capacities range from 120 ml to 240 ml, and configurations include options with or without handles.
Functionally, PPSU bottles are classified into standard models and anti-colic models. The anti-colic variants work by minimizing air intake during feeding, thereby reducing instances of gas, burping, and spit-up [1]. For routine sterilization, methods such as boiling, steam sterilization, or microwave heating may be employed; when cleaning, it is essential to use a specialized detergent to thoroughly cleanse both the bottle and the nipple.
