What makes Aoi baby bottles made of PPSU special?

PPSU baby bottles are among the highest-quality plastic baby bottles available on the market today. PPSU is also the chosen material for Aoi baby bottle bodies.

When selecting products for your baby, safety is undoubtedly the top priority for mothers. Understanding the concerns of mothers, during the research and production process, the choice of safe materials is a particular priority for Aoi.

1. What is PPSU?

PPSU (Polyphenylsulfone) is a high-quality and safest plastic material currently available on the market, trusted by many customers for its excellent durability and high safety when in direct contact with food. It has been rigorously tested and certified to meet standards by organizations such as NSF (National Sanitation Foundation) and the FDA (Food and Drug Administration).

2. Advantages of PPSU Material in Making Aoi Baby Bottles

After thorough research, Aoi has chosen PPSU as the material to make the baby bottle bodies. The PPSU material used in Aoi baby bottles is directly imported from BASF, the world’s best PPSU supplier. With its main headquarters in Ludwigshafen, Germany, BASF has subsidiary companies and joint ventures in over 80 countries, 6 synthesis sites, and 390 other production sites worldwide.

The PPSU material used in Aoi baby bottle bodies offers remarkable advantages:

2.1. Safety for your baby :

PPSU plastic has been certified to meet standards by NSF (National Sanitation Foundation) and FDA (Food and Drug Administration). Aoi baby bottles made from PPSU plastic do not contain any endocrine-disrupting chemicals like BPA and BPS. This ensures that mothers do not need to worry about the safety of the bottles when used with their babies.

Furthermore, PPSU baby bottles are resistant to odors, dirt buildup, chemical resistance, and prevent bacteria accumulation. This ensures better intestinal health for your baby, reducing the risk of digestive disorders.

2.2. Excellent heat resistance and thermal conductivity:

PPSU baby bottles exhibit excellent heat resistance, withstanding temperatures of up to 200 degrees Celsius. This means that when mothers sterilize the bottles using boiling water or a microwave, the bottles will not deform or release harmful substances. Additionally, PPSU bottles’ good resistance to hydrolysis makes them suitable for repeated steam sterilization. Their excellent thermal conductivity also allows for quicker heating and cooling compared to regular bottles.

2.3. Super durability, lightweight, and high resistance to breakage:

PPSU material is highly durable and can withstand strong impacts, such as being dropped or bumped, without the risk of shattering. This exceptional durability ensures a long product lifespan, helping mothers save on replacement costs. Another notable feature of PPSU material is its resistance to scratches, ensuring that the bottle’s surface remains fresh and clean. Its lightweight nature is also a significant advantage.
