Syensqo (Solvay Specialty Polymers) Veradel® A-301 Polyethersulfone (PESU) (Unverified Data**)
Categories:	Polymer; Thermoplastic; Polyethersulfone (PES)
Material Notes:	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 Acid Resistant; Chemical Resistant; Creep Resistant; Flame Retardant; Food Contact Acceptable; General Purpose; Good Adhesion; Good Dimensional Stability; Good Thermal Stability; Good Toughness; High Heat Resistance; High Tensile Strength; Hydrolysis Resistant; Medium Flow; Medium Molecular Weight; Medium Rigidity Uses: Appliance Components; Appliances; Automotive Electronics; Batteries; Business Equipment; Electrical Parts; Electrical/Electronic Applications; Food Service Applications; Industrial Applications; Microwave Cookware Processing: Compounding; Injection Molding Agency Ratings: FDA Food Contact, Unspecified Rating; NSF STD-51 Automotive Specifications: ASTM D6394 SP0213 Availability: Africa & Middle East; Asia Pacific; Europe; Latin America; North America Information provided by Solvay Specialty Polymers.
