BASF is expanding its portfolio of certified biomass-balanced polyarylethersulfones with Ultrason P 3010 BMB, a polyphenylsulfone (PPSU) with 20% attributed bio-circular feedstock. Ultrason P 3010 BMB enables customers across industries like household and catering, water and sanitary, medical technology, hydrogen production and E&E to increase the use of renewable resources and accelerate their transition toward a more circular economy. This addition to the Ultrason portfolio thus helps them to achieve their sustainability goals without compromising on the material’s performance, its quality or the need for investments in new machinery.

With Ultrason P 3010 BMB, the fossil raw materials used at the beginning of production are partly replaced by renewable feedstock derived from organic waste and residual biomass. This bio-circular feedstock is attributed to the Ultrason P grade via a mass balance approach which is certified according to ISCC PLUS (1). The BMB grade also benefits from 100% green electricity used in a resource-efficient, continuously emission-optimized process in the production plant in Ludwigshafen, Germany. This method allows customers to benefit from a drop-in solution that is chemically identical to the standard Ultrason P 3010 grade. As a result, no re-qualification of applications or changes in processing parameters are necessary.

Same performance – supporting customers’ sustainability goals
“With Ultrason P 3010 BMB, we are helping customers advance their green transformation at an early stage of their sustainability journey,” said Nami Lohbeck from global business management Ultrason at BASF. “By choosing Ultrason^® P 3010 BMB, customers can contribute to the substitution of fossil resources, increase the use of renewable raw materials, and differentiate their products from the competition through added sustainability benefits.” Like its standard counterpart, Ultrason^® P 3010 BMB offers the excellent high-temperature stability, chemical resistance, toughness and long-term durability expected from BASF’s PPSU materials. Customers can rely on the same performance and certification status, including suitability for applications that demand rigorous safety and quality, e.g. baby bottles, components in contact with drinking water and medical devices. In 2025, BASF was the first company to introduce biomass-balanced polyethersulfone (PESU), i.e. Ultrason E 2010 BMB with 39% attributed bio-circular feedstock certified by ISCC PLUS.

Ultrason^® is the trade name for BASF’s product range of polyethersulfone (Ultrason^® E), polysulfone (Ultrason^® S) and polyphenylsulfone (Ultrason^® P). The high-performance thermoplastic is used to manufacture water filtration membranes, stylish, durable and safe household and catering applications as well as lightweight components for the automotive and aerospace industries. Ultrason^® brands can substitute thermosets, metals, glass and ceramics in many applications because of their extraordinary property profile.
