Solvay Advanced Polymers introduces transparent high-temperature polymer

A totally new transparent high-temperature sulphone polymer, Supradel HTS, is being introduced by Solvay Advanced Polymers Llc at the K2004 International Trade Fair, Hall 6 Stand D76, 20-27 October 2004 in Düsseldorf, Germany.

With a glass transition temperature of 265C (509F) and a heat deflection temperature of 255C (491F), this new aromatic sulphone polymer offers the highest heat resistance of any transparent amorphous thermoplastic polymer commercially available today.

Supradel HTS is the first totally new sulphone-based polymer to be introduced commercially in the last 15 years. 'The material's unique combination of transparency, high heat resistance, and dimensional stability represents a technological breakthrough and makes it an important addition to our line of ultra-performance polymers,' said Doug Brademeyer, global business manager for Solvay Advanced Polymers. Brademeyer added that the polymer has been produced in commercial quantities.

Supradel HTS offers the highest glass transition temperature of any fully thermoplastic resin commercially available today. This exceptional thermal performance is available along with other performance features traditionally associated with sulphone polymers. These features include good strength, stiffness and dielectric properties over a wide temperature range; resistance to hydrolysis by hot water and steam; excellent resistance to acids and bases; and inherent flammability resistance.

It offers a distinct advantage over many polyimides because it can be melt processed, which offers better manufacturing economics than solution casting or compression moulding. Supradel HTS also provides significant performance advantages over thermoplastic polyimides, which include resistance to bases, improved melt stability during fabrication, and a robust amorphous chemical structure that is capable of holding tight dimensional tolerances.

Supradel HTS can be processed by conventional thermoplastic techniques, including injection moulding, extrusion, and thermoforming. Because of its processing versatility and high heat resistance, it is a viable material in engineering applications having high-temperature requirements. This includes automotive, aerospace, electrical, electronic and industrial product applications.

The material's thermal performance, combined with its good strength and stiffness, dimensional stability and creep resistance opens the door to high-temperature injection moulding applications that traditionally have been limited to filled, semicrystalline polymers, such as glass-filled PEEK.

Supradel HTS is expected to offer improved dimensional control relative to glass-filled PEEK for applications having complex part geometries or tight dimensional tolerances. The performance characteristics mentioned above combined with the material's good processing economics also make Supradel HTS a good candidate for metal replacement.

Supradel HTS is a strategic addition to the company's line of ultra-performance polymers, which include Torlon polyamide-imide and Kadel aromatic polyketone. It also expands its broad portfolio of high-performance sulphone polymers, which include Radel R polyphenylsulphone, Acudel polyphenylsulphone blends, Radel A polyethersulph one, Udel polysulphone, and Mindel polysulphone blends.
