...d from this are mounted on the wing leading edges and are about 20% lighter than the aluminium part used until now, which saves fuel costs. Also on board, in the form of transparent partitions between the different seating categories, is Radel R 7000 tr from Solvay. Polyphenylsulphone’s premiere in the Airbus was expedited by its high transparency, notch impact resistance and low environmental stress cracking. With a glass transition temperature of 265°C and a heat deflection temperature of 255...

Kunststoffe international, 2005-11-21, Impressive Variety: Polysulfones (PSU, PESU, PPSU)
...one 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 moderately he...

...olyphenylsulfone (PPSU) in particular is a material of choice, since with steam sterilisation temperatures of 134°C must be tolerated for 18min a thousand times or more. Thanks to its thermal properties, this poses no problem for the PPSU grade Radel R from Solvay Advanced Polymers, which has a glass transition temperature of 220°C and an exceptional heat distortion temperature (HDT) A-value of 207°C. However, other criteria must also be met. For instance, the mechanical properties – above all, ...

Kunststoffe international, 2005-11-21, Sulphone Polymers: Clear Vision
...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 R PPSU have values of 204°C an...

Tests with the high-performance plastics PEI (grade: Ultem; manufacturer: Sabic Innovative Plastics), PPSU (grade: Radel R; manufacturer: Solvay GmbH) and PEEK (grade: Victrex PEEK; manufacturer: Victrex plc) produced strips in a quality that cannot be attained through the conventional form of production by injection molding or extrusion. A large number of special inje...

...solely by Sabic. In 2006, Solvay, too, launched new, directly metallizable polyethersulfones for the lighting sector. They are designed for operating temperatures of up to 205°C and are notable for their high melt flow rates (Radel LTG-3000 PES). In particular, it is difficult to realize new ideas such as cornering lights or highly stylized daytime running lights without PESU or PEI due to the high demands on the geometry. Free-flowing polysulfones, such as Udel LTG-2000 (manufacture...

Manufacturers, Capacities, Production After the takeover of Gharda by Solvay in 2006, and the subsequent portfolio optimization, with substitution of the Gafone brands with Veradel brands, there are still three large producers of polyarylsulfones in the world: BASF SE, Ludwigshafen, Germany, Solvay, Brussels, Belgium, and Sumitomo, Sendai, Japan. The associated production capacity increased by more than 30 % in the past fi...
