The Japanese manufacturer of baby products Zoom T in Tokyo has selected BASF’s Ultrason P to manufacture baby bottles marketed under its Dr. Bétta brand. Polyphenylsulfone (PPSU) meets Zoom T’s stringent requirements for its curved bottles as they are safe and easy to handle. Ultrason P 3010 nat is approved for contact with food and stands out for its excellent strength, chemical resistance and resistance to very hot steam up to 180 ° C. These properties ensure safety when using the bottles, which are also lightweight and do not produce splinters if broken. They can be used for a long time without losing their mechanical and optical qualities. The transparent and soft honey colored Ultrason P 3010 material can be easily sterilized in microwaves or in very hot water. The BASF PPSU allows the design of complex shapes such as Bétta bottles as it is also suitable for blow molding and extrusion.

Ultrason® P 3010 outperforms PPSU materials on the market to make baby bottles due to its excellent melt stability necessary for the blow molding and extrusion process to produce bottles of its brand Dr. Bétta. Polyphenylsulfone (PPSU) meets Zoom T’s stringent requirements for its curved bottles, which are safe and easy to handle. Ultrason P 3010 nat is approved for contact with food and exhibits excellent strength, chemical resistance and resistance to superheated steam up to 180 ° C). These properties ensure that the bottles are safe to use, while being lightweight and inviolable. They can be used for a long period of time without losing their mechanical and optical qualities.

“We are aware that Ultrason is also used in sensitive applications and even in medical devices thanks to its extraordinary quality. That is why we rely on this material as our goal is to offer maximum safety for our Bétta bottles ”, says Tomoko Kawai, President and CEO of Zoom T.“ This exclusive material from PPSU makes our bottles easy to handle, durable, very Strong and lightweight, perfect for busy moms and dads. With Ultrason P we can perfectly reproduce the curved geometry of our Bétta bottles by blow molding and extrusion. This is important as the curved design prevents babies from inhaling air while breastfeeding, thus avoiding ear infections or colic. “

During extrusion blow molding, molten plastic is extruded through a die to form a tube-shaped “parison.” The internal pressure is then used to inflate the molten parison towards the walls of a mold, so that the part achieves its shape. This flexible process also allows complex geometry parts to be molded with various thicknesses and designs. Medium viscosity Ultrason P 3010 nat material is especially suitable for this process due to its high inherent stability to melt. This allows the elongated, hot parison to remain stable even near the hot die, thus ensuring uniform blow molding.
