    Ultrason® (PSU, PESU, PPSU) – the special plastic for high-quality parts

      Our Ultrason® grades are materials especially designed for applications that require high heat resistance ‒ they always keep stiffness and dimensional stability even when used at very high temperatures. Their wide spectrum of properties allows them to be molded into high-quality engineering parts and highly stressed mass-produced articles.

      Ultrason® E, S, P (PESU, PSU, PPSU)

      The Ultrason® resins are amorphous thermoplastics derived from polyethersulfone (PESU), polysulfone (PSU) and polyphenylsulfone (PPSU) and offer very high resistance to heat. Their wide spectrum of beneficial properties allows them to be molded into high-quality engineering parts and high-load mass-produced articles. They can be processed by almost all the techniques adopted for thermoplastics.

      Ultrason® can be successfully used for applications in which other plastics, e. g. polyamide, polycarbonate, polyoxymethylene and polyalkylene terephthalates, fail to meet the requirements. By virtue of their extraordinary versatility, Ultrason® resins can substitute thermosets, metals and ceramics.

      The world's first particle foam based on polyethersulfone

      • Prototypes with unique combination of properties: lightweight, stiff and strong, highly temperature resistant, intrinsically flame retardant
      • Suitable for complex-shaped components in cars, airplanes and trains

      After two years of intensive research, BASF is now able to present prototypes of the world's first particle foam based on polyethersulfone (PESU).

      The foam is characterized by its unique combination of properties:

      • high-temperature resistance
      • inherent flame retardancy
      • extremely light while stiff and strong

      It is therefore particularly well suited for complex-shaped components in cars, airplanes and trains, which require excellent mechanics together with the ability to withstand high operating temperatures or meet stringent flame-retardant requirements. The expandable PESU granulate is pre-foamed into beads with low densities between 40 and 120 g/L and can be processed into molded parts with complex 3D geometries using technologies available on the market.
