BASF’s Ultrason® grades are 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.

So Ultrason® is suitable for many applications in automotive construction, in the food and household sectors, but also for membranes used for water filtration as well as electric and electronic components.

The extraordinary property profile of Ultrason®:

high stiffness

high mechanical strength

low dependence of the properties on the temperature

very high long-term service temperature

favorable dielectric properties

very favorable behavior in case of exposure to fire

excellent hydrolysis resistance

good dimensional stability

good electrical insulating capacity
