High-temperature polymer


When things get really hot, the right choice is Ultrason. Grades within the Ultrason family can withstand temperatures up to 428°F. For example, sterilizable baby bottles made from Ultrason retain their transparency and are resistant to breakage even after numerous machine washings.


For almost 20 years, BASF has produced high temperature Ultrason S PSU and Ultrason E PES. Recently, BASF added Ultrason PPSU for even more demanding applications. The result is a well rounded performance material portfolio.


The applications for these performance materials span the electronic, automotive and consumer industries. Ultrason S and Ultrason E are often used where requirements exceed the capabilities of polyamide, polycarbonate, polyoxymethylene and polyalkylene terephthalate. The exceptional property spectrum of these materials even allows them to replace thermosets, metals and ceramics.


Replace polycarbonate with Ultrason when you require:


    FDA and European food contact compliance
    Sterilizable and long-term dishwasher safe
    Impact resistance
    No discoloration by food contact
    High mechanical strength and toughness
    Dimensional stability
    Easy coloring
