Best Impact & Steam Resistance to 400°F (205°C)
|
- Impact resistant
- Highly resistant to steam autoclaving
- High modulus of elasticity and heat resistance
Radel® R polyphenylsulfone (PAES) is an amorphous
high performance thermoplastic offering better impact resistance
and chemical resistance than polysulfone and polyetherimide (Ultem
PEI).
Radel 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
outlasting other materials by a factor of 40:1. This factor makes
it an excellent choice for medical devices as steam autoclaves
are widely used to sterilize medical devices. It also resists
common acids and bases-including commercial washing solutions-over
a broad temperature range.
Radel R is available in transparent, 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 USP Class VI compliant.
It is suitable for use in electronic assembly equipment and devices
that must withstand solder temperatures. Radel has a heat deflection
temperature of 400°F (205°C).
Application
Medical wands - Radel rod is intricately machined into smooth, comfortable
handles used as structural components in medical applications.
These handles offer superior impact resistance and autoclavability
(Prior material:Stainless Steel).
Endoscopic probe positioning ferrule - or endoscopic surgical devices, a positioning ferrule on the instrument handle is intricately machined from Radel R rod (Prior material: Stainless Steel).
Engineering Notes:
Although Radel R has been approved for use in a variety of medical devices, it is not FDA compliant and so it is not appropriate for food contact applications. Radel is not a wear material, and its properties degrade when exposed to sunlight.
