    AI Overview
    Polysulfone (PSU) 4040 typically refers to 4-inch by 40-inch microfiltration or ultrafiltration membrane elements or specialized permeate tubes. These tubes are characterized by high-temperature stability, steam sterilizability, and high chemical resistance, making them ideal for pharmaceutical, food, and high-pressure water treatment applications. 
    Key Features & Applications 
    • Dimensions: Specifically designed for 4x40 inch membrane housings, common in industrial, food & beverage, and medical systems.
    • Performance: Polysulfone provides high compaction resistance for high-pressure systems, high hydrolysis resistance for autoclaving, and compatibility with a pH range of 2–13.
    • Types:
      • Permeate Tubes: Used as central cores for membrane elements (e.g., 4040/8040 Manufactured by Defilter).
      • Microfiltration Elements: WaterAnywhere offers 4x40-inch polysulfone membrane elements.
      • Tubing: American Granby provides poly tubing.
    • Advantages: Superior dimensional stability, transparency, and resistance to surfactant and hydrocarbon oils. 
    Typical Properties 
    • Operating Temp: Up to
      150∘
      C
       or
      320∘
      F
      .
    • Structure: Transparent, rigid, and high-strength amorphous thermoplastic.
    • Compatibility: Resistant to mineral acids, alkali, and electrolytes. 
    Alternatives
    For different industrial needs, options include DuPont FilmTec™ TW30 PRO-4040 elements which are used for water treatment.
