PPSU Rod

PPSU Rods are part of our extensive range of polymer rods, with 46 variations available. Polyphenylsulfone (PPSU) is a high-performance thermoplastic known for its dimensional stability, toughness, and resistance to heat and chemicals. Its combination of properties makes these rods suitable for applications requiring sterilization and for precision parts in analytical equipment, semiconductor manufacturing and aerospace components. These versatile thermoplastic rods can be machined, bonded or welded to create custom components.
