MATERIALS | HIGH TEMPERATURE
Comotomo uses Avient’s Colorant Chromatics high-temperature blue colour formulation and BASF’s Ultrason P 2010 PPSU compound in this bottle ring component
phone (PPSU) compounds. Estonian electrolyser manufacturer Stargate Hydrogen is using Ultrason PSU to make the frames in its stacks used for alkaline water electrolysers, which produce hydrogen from water. The PSU replaces metals such as nickel, resulting in much lighter stacks. This is possible because the material offers high temperature and chemical resistance in harsh alkaline conditions and can withstand high stack pressures. Because it can be injection moulded, it provides greater design flexibility than metal. The patent-pending design of the stacks
performance and miniaturisation. These new grades will accelerate expansion into a broader range of applications and product development through two approaches: versatility in meeting diverse design needs; and high flowability.
LCP production The LH series has well-balanced performance, combining flowability, mechanical properties and heat resistance. Their adaptability allows them to accommodate a range of product designs, making them suitable for various component applications. The TF series is engineered for high fluidity for better moulding of complex geometries found in smartphones and precision electronic components. While maximising flowability, the TF series also maintains excellent mechanical properties and a flexible moulding window, providing materials that support miniaturisation and high-density integra- tion in electronic devices. Produced in Japan and Taiwan, Laperos LCP has an annual production capacity of 20,000 tonnes. Its properties include high mechanical strength, heat resistance and coefficient of linear thermal expansion. Also in LCPs, Sumitomo Chemical has devel- oped a mass production technology to make LCPs from a bio-derived monomer. In the new manufac- turing process, Sumitomo has adopted a ‘segrega- tion approach’ that separates biomass materials from others during production. This enables precise control of the biomass content and can clarify how much is included in the product. It also uses the mass-balance approach. Sumitomo aims to begin supplying the product from 2027. BASF produces a number of materials with high-temperature capabilities, including its Ultrason brand of PPS, PSU and polyphenylsul-

incorporates frames with a diameter of 85 cm. Ultrason enables them to be large, robust, and durable, with a focus on higher operating tempera- tures and longer lifetimes. Its stable mechanical properties make it suitable for current (90°C) and future (>100°C) electrolysers.
Baby bottle
BASF has been involved in a collaboration with Avient and Comotomo, a South Korean manufac- turer of infant care products. In Comotomo’s next-generation silicone baby bottle, the over- moulded ring provides structural support and is made from BASF’s Ultrason P 2010 PPSU coloured with Avient’s customized blue colour formulation. Avient said its Colorant Chromatics high-tempera- ture colour technology enables Comotomo to achieve its desired colour and aesthetic for brand identification and consumer appeal while helping it meet strict food-contact safety regulations for infant products. Using Ultrason P 2010, the ring component
offers several performance advantages for baby bottles, including exceptional chemical resistance, excellent dimensional stability, and resistance to superheated steam sterilization. The material can withstand cleaning in dishwashers, boiling water, microwave ovens, and bottle sterilizers. Ultrason P 2010’s high heat resistance and impact strength also enable it to endure the high temperatures and pressures during the silicone overmoulding process used in manufacturing. Polyamide producers, such as BASF, have been making progress in the area of heat resistance. BASF says its portfolio of PA66/6T compounds fills the gap between conventional PA66 and polyph- thalamide (PPA). It says its Ultramid T6000 outper- forms PA66 in mechanical and dielectric properties in humid, high-temperature environments. Its lower moisture absorption ensures good dimensional stability, closing the gap on its own PPA portfolio. Ultramid T6000 allows for easy processing at
