Syensqo (Solvay Specialty Polymers) Veradel® A-301 MR Polyethersulfone (PESU)
Categories: Polymer; Thermoplastic; Polyethersulfone (PES)

Material Notes: Veradel® A-301 MR is a medium melt flow grade of polyethersulfone (PESU) with mold release. 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 MR 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 MR NT

Applications: Appliance Components; Appliances; Automotive Electronics; Batteries; Business Equipment; Electrical Parts; Electrical/Electronic Applications; Food Service Applications; Industrial Applications; Microwave Cookware

Features: 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
