Veradel® 3250 polyethersulfone (PESU) has a slighly higher melt flow rate than Veradel® 3200. This transparent resin offers a high heat deflection temperature, 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® 3250 is FDA compliant and is therefore approved for direct food contact. Other grades available: Veradel® 3200, a low melt flow grade; Veradel® 3300, a medium melt flow grade suggested for general purpose injection molding; Veradel® 3400, a high melt flow grade designed for easy molding of parts with thin walls or long flow lengths and Veradel® 3600, a very high melt flow grade suggested for compounding, especially of glass or carbon fiber reinforced compounds. |
