Polyethersulfone (PES) is a high temperature amorphous thermoplastic offering a superior combination of better chemical resistance and higher dry heat capability than polysulfone (Udel®) or polyetherimide (Ultem®).
Radel® A PolyEtherSulfone or PES (also known as PolyArylEtherSulfone or PAES) provides a greater margin of performance in such areas as toughness in comparison with other plastics. High resistance to heat and combustibility, low smoke emission, and transparency are the combination of properties possessed by components made from PES. These, coupled with light weight, good impact resistance, dimensional stability, and chemical resistance, make PES useful in the electrical/electronics, aerospace/aircraft, automotive, and mass transit industries.
Radel® A is FDA approved and NSF and UL listed. It is available in amber transparent and opaque colors. Glass-fiber reinforced polyethersulfone grades are also available. The addition of glass fibers increases the rigidity, tensile strength, creep resistance, dimensional stability, and chemical resistance of the material. Glass-filled PES is opaque, grayish in color.
