BASF’s Ultrason® grades are transparent, high-temperature resistant, amorphous thermoplastics derived from polysulfone (PSU), polyethersulfone (PESU) and polyphenylsulfone (PPSU). Their wide spectrum of properties allows them to be molded into high-quality engineering parts and highly stressed mass-produced articles. They can be processed by almost all the techniques adopted for thermoplastics.

This combination of features, coupled with ease of fabrication, has enabled Ultrason® to be applied in a wide and increasingly diversified range of applications. Ultrason® can be successfully used for applications in which other plastics, such as polyamide (PA), polycarbonate (PC), polyoxymethylene (POM) or polyalkylene terephthalates (PET, PBT), fail to meet the requirements. By virtue of their extraordinary versatility, Ultrason® resins can substitute thermosets, metals and ceramics.
