Event Details:
Event: 25th Academic Congress of the Chinese Orthopaedic Association (COA 2026)
Date: November 12–14, 2026
Location: Guangzhou, China
Booth: 20.2-G32
Featured Products: Medical-grade PPSU and PSU materials
Organized by the Chinese Medical Association and its Orthopaedic Branch, COA 2026 brings together medical professionals, researchers, and industry representatives to explore developments in orthopaedic care, surgical technologies, and medical innovation.
Shengwen looks forward to connecting with industry professionals and discussing high-performance material solutions for reusable medical devices and orthopaedic instruments.
As medical devices and surgical instruments undergo repeated sterilization and disinfection, material performance plays an important role in their durability and reliability.
High-performance engineering plastics offer manufacturers alternatives to traditional metal and glass components, particularly where heat resistance, chemical stability, dimensional consistency, and mechanical strength are required.
At COA 2026, Shengwen will introduce its sulfone-based engineering plastics, with a focus on PPSU and PSU grades for demanding medical applications.
Polyphenylsulfone (PPSU) is a high-performance thermoplastic known for its toughness, heat resistance, and hydrolytic stability. It is particularly suitable for reusable medical components exposed to repeated high-pressure steam sterilization.
Key material properties include:
Continuous service temperature of up to 180°C and heat deflection temperature of 196°C.
Resistance to repeated steam sterilization at 134°C.
Inherent flame retardancy meeting UL94 V-0.
High impact strength of up to 690 J/m.
ISO 10993 biocompatibility testing reports covering cytotoxicity, skin sensitization, and intracutaneous irritation.
Medical-grade PPSU can be machined into sterilization trays, surgical instrument handles, instrument components, medical connectors, and other reusable device parts.
Polysulfone (PSU) offers a combination of heat resistance, transparency, dimensional stability, and hydrolytic stability. Its amber-transparent appearance makes it suitable for components where visual inspection is required.
Key material properties include:
Continuous service temperature of up to 160°C.
Heat deflection temperature of 175°C.
Hydrolytic stability for applications involving repeated steam sterilization.
Resistance to chemical disinfection.
Typical applications include sterilization trays, dialysis components, ventilator humidifier chambers, medical connectors, equipment housings, and laboratory fixtures.
In addition to standard rods and plates, Shengwen will present its thin-sheet solutions for fabricated medical components and equipment housings.
Available sheet thicknesses range from 2 mm to 5 mm, supporting applications that require specific dimensions and material configurations. Standard rod and plate sizes are also available, with dimensions ranging from 5 mm to 100 mm.
Both medical-grade and industrial-grade materials are available to meet different application requirements. For projects requiring customized dimensions, colors, or modified material grades, Shengwen also supports tailored solutions through its customization services.
Throughout the three-day exhibition, Shengwen's technical and sales teams will be available at Booth 20.2-G32 to discuss material selection, processing requirements, and application-specific needs.
Visitors can consult the team on:
Material Selection: Recommendations on suitable PPSU and PSU grades for specific medical applications.
Performance Comparison: Discussions on material properties and requirements for reusable medical devices.
Customized Specifications: Options for sheet, rod, and plate dimensions, as well as modified material grades.
Sample Development and Supply: Coordination of sample evaluation, prototyping, and bulk supply requirements.
