Syensqo (Solvay Specialty Polymers) Supradel® HTS-2401 High Temperature Sulfone Resin  (discontinued **)
Categories: Polymer; Thermoplastic; Polysulfone (PSU)

Material Notes: Supradel HTS-2401 is a high-temperature high-performance amorphous sulfone polymer designed for use in reinforced high temperature thermoplastic formulations. With its glass transition temperature of 245 °C and HDT of 235 °C, the resin extends the thermal capability range available in other sulfone polymers.

The resin is completely amorphous and fully thermoplastic allowing easy melt fabrication by means of injection molding and other thermoplastic processing techniques. Along with its high thermal performance capabilities, HTS-2401 resin also boasts a long list of high performance attributes which include excellent hydrolytic stability, resistance to acids and bases and inherently flame retardant performance to mention a few.

The ease of melt fabrication, coupled with the completely amorphous character assures tight dimensional control during injection molding of precision parts and components. The versatile performance profile of HTS-2401 makes it a good candidate for metal replacement or the replacement of difficult-to-process thermoplastics in a wide range of engineering applications.

In its natural state, Supradel HTS-2401 resin is transparent with an amber/brown color.
