Ultra-performance polymer offers heat resistance of transparent amorphous thermoplastic polymer

Solvay Advanced Polymers Llc : 11 September, 2006  (New Product)
A totally new transparent high-temperature sulfone polymer, SUPRADEL HTS, is being introduced by Solvay Advanced Polymers, L.L.C. at the K2004 International Trade Fair, Hall 6 Stand D76, in D
SUPRADEL HTS is the first totally new sulfone-based polymer to be introduced commercially in the last 15 years. ďThe materialís 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,Ē said Doug Brademeyer, global business manager for Solvay Advanced Polymers. Brademeyer added that the polymer has been produced in commercial quantities.

Properties 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 sulfone 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.

Distinct Among Ultra-Performance Polymers
SUPRADEL HTS offers a distinct advantage over many polyimides because it
can be melt processed, which offers better manufacturing economics than solution
casting or compression molding. 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.

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

The materialís thermal performance combined with its good strength and
stiffness, dimensional stability, and creep resistance opens the door to high-temperature injection molding 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 materialís good processing economics also make SUPRADEL HTS a good candidate for metal replacement.
