PES material is a high temperature engineering thermoplastic that can withstand high temperatures over long periods of time. The chemical abbreviation for polyethersulphone has long been PES. However, due to current standards such as EN ISO 1043:2011, polyethersulfones are now referred to as PESU in order to better assign them to the sulfone family. However, as PESU is not yet widely used, we will continue to use the abbreviation PES here.
PES polymer offers high mechanical strength and stiffness as well as relatively low notch sensitivity. In addition, PES has good chemical compatibility and hydrolysis resistance. Thanks to its amorphous molecular structure, PES plastic material is translucent and has a yellowish brown, transparent colour. PES material is ideal for applications with tight tolerances and low dimensional change over a wide temperature range. Polyethersulfone components, regardless of nomenclature, are ideal for a wide range of applications due to their strong physical properties.
PES semi-finished products are manufactured by Ensinger under the brand name TECASON E. As manufacturer of polyethersulfone semi-finished products we offer PES shapes in the form of
The Ensinger TECASON E family offers the following polyethersulfone modifications:
PES polyethersulphone, along with PPSU and PSU, belongs to the polyarylsulphone group. Although each material has some similar properties, there are subtle differences that make each material unique in its own way. For example, PES offers higher chemical resistance and impact strength than PSU. Flame retardancy, transparency and manufacturing versatility make PES a useful member of the polyarylsulphone family. Other benefits of PES plastic material include
