BASF offers polyphenylsulphone (PPSU) for manufacturing bottles by injection stretch blow molding, extrusion blow molding and injection molding. Bottles manufactured using Ultrason® P portfolio are of high-quality, safe for for adults and babies, robust and chemically resistant as well as available in numerous designs, shapes and colors. All three processing methods benefit from the customized properties of the high-temperature thermoplastic: It contains no harmful substances, is approved for food contact and has outstanding strength, chemical resistance and long-term high-temperature stability up to 180°C. Bottles made from the transparent, slightly honey-colored BASF polyphenylsulphone can easily withstand sterilization in a microwave or in very hot water – regardless of the method used to manufacture them.
“The production of high-quality, safe and stylish bottles for adults and babies presents a challenge that cannot be compared to that of conventional PET, PP or co-polyester bottles,” says Georg Grässel from BASF’s global business development Ultrason®. “The globally widespread processing methods all have their own specific requirements of the material used – and this is where Ultrason® P has proven its value to customers in many different countries. They can choose the most suitable material from our portfolio and can also benefit from our on-site technical application support and the global availability of the different grades.”
在挤出吹塑过程中,塑料熔体extruded from top to bottom through a circular die to form a tube-shaped parison. Internal pressure is then used to inflate the parison within a mold thus giving the part its shape. The medium-viscosity Ultrason® P 3010 is particularly suitable for this process due to its inherent high melt strength in contrast to other PPSU materials on the market. This allows the hot, elongated parison to remain stable even near the die, ensuring uniform blow molding. For complex geometries with different wall thicknesses and designs, a programmed parison control can be used. This prevents elongation of the parison caused by the parison’s weight and results in uniform wall thicknesses over the complete length of the bottle.
当使用注射成型时，可以将瓶子主体塑造为有或没有盖螺纹和底座，在瓶装设计或用于发泄婴儿瓶的方法时，它具有极大的灵活性。如今，具有单一和多腔模具的制造与上游热门跑步者系统结合使用，这是最新的。高流量，低粘度Ultrason®P2010特别适合于此，因为即使有较长的流动路径，它也使薄壁成为可能，而不会损害撞击或耐化学性。
最广泛的制造过程，特别是对于亚洲的婴儿瓶，是注射弹力吹塑。首先，在注射模中产生了看起来像带帽螺纹的试管，然后重新加热并最终在吹风模中膨胀并充气，该吹风模构造了瓶子设计为负。Ultrason®P3010的优点主要是在快速周期的时间和瓶盖线的精确成型中找到的。
两种Ultrason®P等级均适用于注入成型和注入拉伸吹塑成型，因为它们使用适当配置的热跑者系统而无需废丢失，它们特别易于处理。这使得可以使用Ultrason®P生产瓶子，该瓶可以长时间使用，并且在许多不同的应用区域中，而不会损害机械和光学性能的质量。
Ultrason®是BASF产品范围（Ultrason®E），Polysulfone（Ultrason®S）和Polyphenylsulfone（Ultrason®P）的产品系列。高性能材料还用于在电子，汽车和航空航天工业以及水过滤膜以及与热水和食物接触的部分中生产轻量级组件。由于其非凡的财产概况，Ultrason®品牌可以在许多应用中替代热衣，金属和陶瓷。
