What is Radel® R-5600 NT

In high-standard industries such as aerospace, food service and medical applications, the reliability, safety and performance of materials often determine whether a product can win market recognition. As a high-performance polysulfone (PPSU) material developed by Solvay, Radel® R-5600 NT, with its outstanding transparency, thermal stability and chemical resistance, has become an ideal solution for many harsh environments.

01 | Material Highlights and Core Characteristics

Excellent flame retardancy: The material itself meets the UL94 V-0 flame retardant grade, ensuring safety without the need for additional additives.

High-temperature resistance and steam sterilization: Even in an environment of repeated high-temperature steam sterilization, it can still maintain its strength and transparency.

Outstanding chemical and alkali resistance: Compared with traditional transparent plastics such as PC and PEI, Radel® R-5600 NT has more advantages in acidic, alkaline and chemical contact environments.

Stress crack resistance: It can maintain long-term structural stability even under continuous stress or complex mechanical loads.

Optical transparency: Available in clear transparent or amber color options, it not only meets functional requirements but also takes into account design aesthetics.

02 | Typical Application Fields

Food service industry: Suitable for high-end catering utensils and drinking water system components that can be repeatedly disinfected.

Aerospace Industry: Due to its lightweight, high heat resistance, and flame retardant properties, it is widely used in aircraft interior components.

Medical and laboratory: It performs outstandingly in situations that require repeated high-temperature sterilization, such as medical containers, transparent casings, and laboratory equipment.

Electronic and electrical: Thanks to its excellent electrical insulation and long-term heat resistance index (RTI), it also has application value in the protection of some electronic components.
