Why Udel
Udel is the brand designation for Syensqo’s* polysulfone or PSU polymer. The melt-processable thermoplastic can be injection molded, and extruded into stock shapes for machining.
Performance attributes of Udel PSU include high structural strength, toughness, resistance to high temperatures and chemicals, and resistance to all common sterilization methods.
Does Udel Polysulfone Comply with ISO 10993 Biocompatibility Standards?
Udel polysulfone grade are available that comply with the requirements of ISO 10993 for devices that are in contact with bodily tissue and fluids for up to 24 hours.
How Does Udel Polysulfone Compare to Other Transparent Medical Plastics?
Polycarbonate (PC) and acrylic (PMMA) are transparent plastics commonly used in medical applications. Polysulfone has a significant advantage compared to both of these materials in its ability to withstand far more cycles in steam sterilization without a significant drop in strength or ductility. Polysulfone also resists higher temperatures, and has better overall tolerance to common chemicals encountered in the health care environment.
Which Udel Grade Is Used in Medical Devices and Equipment?
Transparent Udel P-1700 PSU has a long history of use in many medical applications including devices that are in contact with internal bodily tissue and fluids for up to 24 hours.
