What is Polyphenylsulfone PPSU

Today, with the continuous emergence of high-demand application scenarios, from operating rooms to food factories to advanced manufacturing industries, traditional plastic materials can no longer meet the comprehensive needs of heat resistance, corrosion resistance, and long-term stability. Solvay PPSU R-5000 NT, a colorless and transparent polyphenylsulfone  PPSU, was born in response to this industry call. With its excellent thermal stability, broad-spectrum sterilization compatibility, and mechanical strength performance, it has become the "ideal choice" in the high-end field.

It not only passed the V-0 and 5VA flame retardant certifications, but also met the composite standards of medical grade, food contact grade, drinking water grade, electronic grade, etc., opening up new space for design freedom and safety boundaries.

01 | Polyphenylsulfone properties: not only heat-resistant and steam-resistant, but also radiation-resistant and sterilization-resistant

Compared with ordinary engineering plastics such as PES and PEI, R-5000 NT is almost full in terms of performance dimensions:

  ・Extreme heat resistance: HDT is as high as 207°C, glass transition temperature is 220°C, and it will not become brittle or deform even if exposed to high-temperature steam environment for a long time;

  ・Broad-spectrum sterilization compatibility: It supports multiple sterilization methods such as ethylene oxide, gamma rays, electron beams, and high-temperature steam, and is the first choice for multiple sterilization medical products;

  ・Chemical and hydrolytic stability: It is acid-resistant, alkali-resistant, and detergent-resistant, and is not afraid of harsh cleaning agents and repeated hot water cycles;

  ・Dimensional stability and stress crack resistance: The linear expansion coefficient is small, and the shrinkage rate is only 0.70%, which can cope with high-precision instrument processing without worries;

  ・Excellent toughness and impact resistance: The cantilever beam notch impact value is as high as 690 J/m, and it can remain unbroken even in low-temperature environments;

  ・Good electrical and wireless transmission compatibility: Good insulation (volume resistivity 9E15 Ω.cm), suitable for wireless sensing environments such as smart medical equipment;

  ・Transparency and optical refractive index: The refractive index reaches 1.672, supporting visualization needs and aesthetic design.

✅ At the same time, the material properties cover multiple specifications such as flame retardant, film, sheet, profile, thermal stability, and medical, truly realizing one material for multiple uses and adapting to diverse manufacturing systems.

02 | Application direction: In which industries does Polyphenylsulfone PPSU R-5000 NT stand out?

  ・Medical devices: Suitable for surgical instrument handles, dialysis connectors, respiratory masks, pipe connectors and other parts that are repeatedly sterilized at high temperatures;

  ・Dental and nursing consumables: such as dental tool housings, saliva suction tube components, and nursing needle and tube equipment;

  ・Food service field: coffee machine components, baby bottles, insulation equipment and other high-temperature food contact components;

  ・Automobile and rail transportation: used for heat-resistant and anti-aging components such as engine compartment hot zones, electrical connectors, and smart sensor housings;

  ・Surgical diaphragms and smart conductive parts: devices that have both structural strength and electrical performance requirements in medical electrical products.

04 | Process adaptability: multiple molding methods are covered in one net

Polyphenylsulfone PPSU R-5000 NT has excellent processing compatibility and is suitable for a variety of thermoplastic processing methods:

  ・Injection molding: suitable for high-precision injection molding of small and large shells of complex medical devices;

  ・Extrusion molding: can produce continuous products such as highly transparent films, plates, and strips;

  ・Blow molding: widely used in hollow products such as milk bottles and containers;

  ・Thermoforming & CNC cutting: suitable for customized medical structural parts, laboratory components, functional sample proofing, etc.

Its melt index is in the range of 14~20 g/10min (365°C, 5kg), with good flowability and high molding efficiency, which is conducive to the production of thin-walled products and complex cavity parts.

05 | Compliance and Standard Testing

Polyphenylsulfone PPSU R-5000 NT not only has excellent performance, but also has strong regulatory endorsement and testing and certification support:

  -Flame retardant grade: UL94 V-0 (full color thickness 0.36mm~3.0mm all meet the standard)

  -Passed FDA, NSF, ISO 10993 and other food and medical contact certifications;

  -Multiple ASTM test standard verification: mechanical, electrical, and thermal data are complete;

  -Biocompatibility evaluation, RoHS and REACH compliance reports are available.

📄 As the standard material for mainstream medical and food-grade products in the world, PPSU R-5000 NT fully supports the technical documentation required for international market entry and medical regulatory registration.
