Kunststoffe international, 2005-11-21, Impressive Variety: Polysulfones (PSU, PESU, PPSU)
...fferent sulfone polymers are available on the market: polysulfone (PSU), polyethersulfone (PESU) and polyphenylsulfone (PPSU). In addition, polysulfone blends have also appeared in a number of marketable products. Sulfone Polymers Performance With Udel (PSU), Radel A (PESU) and Radel R (PPSU), Solvay Advanced Polymers covers all three product areas. Polysulfone blends are available under the trade name Mindel. Compared to using pure PSU, these blends of PSU and engineering thermoplastics with m...

...moulding behaviour), - molecular weight distribution and low-molecular weight components, - morphology and purity of the polymer granulates as well as - available viscosity spectrum. Regarding optical characteristics, special types of Udel (Solvay, PSU) and UltrasonE (BASF; PES) were developed by Solvay and BASF with clearly less intrinsic colour, increased transparency and higher purity (lowered dirt and gel contents). This was possible through process improvements. Today these products can be...

... such as impact strength, transparency, the ability to be coloured and radioluminescence (for x-ray imaging) may occasionally be more decisive. Polysulfone (PSU) is tailor-made for these applications. The glass transition temperature of Udel PSU is 190°C and thus significantly above the sterilisation temperature. The HDT A-value of PSU is 174°C and the RTI (as an indicator of the continuous-use temperature) is 160°C. PSU also has an exceptional resistance to hydrolysis. The required one-hundred...

...olysis and chemicals. Strong: Transparent and Heat Resistant Sulphone polymers, as amorphous materials, are inherently transparent. The Solvay Advanced Polymers range of HT thermoplastics includes three transparent products: PSU, with the trade name Udel; PES with the trade name Radel A, and PPSU with the trade name Radel R. In addition to their good optical properties, sulphone polymers have the highest heat distortion temperature (HDT. Udel PSU has an HDT of 174°C, while Radel A PES and Radel ...

Free-flowing polysulfones, such as Udel LTG-2000 (manufacturer: Solvay), are also starting to compete with polycarbonate and (PC + PEI) blends in lowtemperature areas. The amorphous HT thermoplastics are acting in direct competition 115 here with thermosets (BMC). Despite a signif...

In addition, easy flowing polysulfones, such as Udel LTG-2000 (Solvay) are beginning to compete with polycarbonate and (PC+PEI) blends in lower temperature ranges. The amorphous HT thermoplastics are in direct competition with thermosets here. Despite their significantly higher material price, polyethersulfones...
