GB/T 36374.1-2018

This standard establishes a designation system and classification basis for sulfone polymer moulding and extrusion materials, including polysulfone (PSU), polyethersulfone (PES), and polyphenylsulfone (PPSU). It is applied in the plastics industry for material identification and specification development, enabling consistent naming and property-based categorization for engineering applications such as medical devices, aerospace components, and high-temperature electrical parts. The standard ensures clear communication between material suppliers and end-users during procurement, quality control, and product design.
