Sulfones are amorphous engineering thermoplastics noted for high heat-deflection temperatures and outstanding dimensional stability. These strong, rigid polymers are the only thermoplastics that remain transparent at service temperatures as high as 400°F. Natural color of the sulfone resins is transparent light amber. Continuous use in air or in steam at rated temperature does not cloud, craze, or otherwise destroy their transparency. These resins are also available in opaque colors and in mineral-filled and glass -reinforced compounds, which provide improved strength, stiffness, and thermal stability. Heat aging of the polymers increases tensile strength, beat-deflection temperature, and modulus of elasticity appreciably. However, prolonged heat aging (about a year) decreases toughness, tensile strength, and elongation. Unnotched specimens of the sulfones are extremely tough and do not break in standard impact tests. Sulfone polymers exhibit varying levels of chemical compatibility, depending upon their polymeric structure and the presence of additives such as glass. The sulfone polymer family, which includes UDEL polysulfone, RADEL A polyethersulfone, and RADEL R polyphenylsulfone are amorphous resins that combine excellent thermal stability, high strength and toughness, excellent hydrolytic stability, transparency, and good resistance to environmental stress cracking. Sulfone polymers can be processed following standard methods for injection molding, extrusion, and blow molding . Shapes can be machined for prototype evaluations; film and sheet can be thermoformed on conventional equipment. Sulfone polymers will absorb moisture, and although they are hydrolytically stable, they should be dried before processing. There are several types of molds that can be used to mold sulfone resins . These include two-plate, three-plate, and hot-runner systems . All of these can contain manual or hydraulic slides and other required features . Sulfone resins can be extruded onto wire using a semitubing or tubing crosshead die . Wire inlet temperatures should approximate that of the polymer melt . High drawdown of the polymer melt tube can be achieved with sulfone resins . Solvay Advanced Polymers is a global leader in sulfone polymer development, serving the needs of customers in demanding industries such as healthcare, aerospace, automotive, membranes and plumbing. Sulfonation with sulfuric acid, chlorosulfonic acid, sulfur trioxide, and acetyl sulfate easily provides proton - conducting polymer electrolytes, but these sulfonated polymer electrolytes decompose on heating above 200 deg cel because of desulfonation.
