|---|
| Veradel® A-301 is a medium melt flow grade of polyethersulfone (PESU). It is transparent and offers high heat deflection temperatures, excellent toughness and dimensional stability and resistance to steam, boiling water and mineral acids. Other desirable properties include thermal stability, creep resistance and inherent flame resistance. Veradel® A-301 is suggested for general purpose injection molding. It is FDA compliant and therefore approved for direct food contact. A low flow grade is available as Veradel® A-201. It can be processed by either extrusion or injection molding. This grade was formerly marketed as Radel® A PESU Natural: Veradel® A-301 NT&& |
