Formula: PES
Form: Flake
Material: Polyethersulfone (PES)
Commodity: Polymers
Molecular Weight:
48,000 g/mol
Color:
Natural
Polyethersulfone (PES) polymer flakes are small fragments of a high-performance engineering thermoplastic known for its exceptional durability and resistance to harsh environments. Available in 12 variations, PES can withstand high temperatures, oxidation and radiation, making it an ideal material for demanding applications. Its uses range from medical devices, where sterility and biocompatibility are crucial, to aerospace and automotive components that require robustness under extreme conditions. Additionally, PES’s excellent electrical properties make it suitable for electrical equipment, while its stability is advantageous in the creation of filtration membranes.
