PPSU Bottle Injection Stretch Blow Molding Machine
PPSU is a safe material that does not contain carcinogenic endocrine-disrupting substances (environmental hormone: bisphenol A). Steam sterilization by repeated high-temperature boiling. It has excellent chemical resistance, acid resistance and alkali resistance, and can withstand washing with general liquids and detergents without chemical change. Light weight, drop resistance, safety, heat resistance, hydrolysis resistance, impact resistance.
The PPSU baby bottle is made of ppsu (polyphenylsulfone), the safest new material. It is an amorphous thermal material and does not contain bisphenol A, so it is safe, non-toxic, and has a relatively stable internal structure. It does not deteriorate even after repeated high-temperature sterilization. It has very high heat resistance, no chemical toxins are generated during the brewing and heating process, and can be microwaved. The bottle body is lighter, making the bottle more durable and brittle. In addition, the transparency of the bottle is very high, so the mother can easily observe the condition of the milk.
