Radel ® A PES
Radel ® R PPSU
Radel® is a registered trademark of Solvay Advanced Polymers
The Radel® family of sulfone-based polymers are
high temperature amorphous thermoplastics 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. It has a high
heat deflection temperature of 400°F (204°C), good hydrolytic stability, and
chemical resistance to many commonly used acids and bases.
Radel® A is available in transparent, opaque as well as filled
grades. It is used for lighting fixtures, electrical and electronic
components, surgical and medical devices, chemical process equipment,
automotive and food service components. Radel® A is FDA approved
and NSF and UL listed. It is available in amber transparent and opaque
Radel® R PolyArylEtherSulfone or PAES (also known as
Polyphenylsulfone or PPSU) offers superior hydrolysis resistance when
compared to other amorphous thermoplastics as measured by steam autoclaving
cycles to failure. In fact, Radel® R has virtually unlimited
steam sterilizability. This makes it an excellent choice for medical
devices. It also resists common acids and bases -- including commercial
washing solutions -- over a broad temperature range.
Radel® R is available in amber (translucent), natural (bone
white), and custom colors. It is commonly used in sterilization trays,
dental and surgical instrument handles, orthopedic implant trials and in
fluid handling coupling and fitting applications. Radel® R is
FDA, USDA, and USP Class VI compliant.
