PES - Polyethersulfone
General Information
SUMIKAEXCEL PES of SUMITOMO CHEMICAL is a polyethersulfone which possesses the highest thermal resistance/glass transition temperature among all amorphous polymers.
SUMIKAEXCEL PES is a transparent resin with a slightly amber color having a variety of useful properties, such as heat resistance, creep resistance, chemical resistance, dimensional stability, flame resistance and hot water resistance.
Based on physical form, two types of SUMIKAEXCEL PES are available: granules and powders. Granules grades are suitable for injection molding applications such as automotive, electrical/electronic, telecommunications and aerospace, but also fit for film and extrusion applications. The powder grades are mainly utilized as impact modifier for epoxy-based composites, heat resistant coatings, adhesives and membrane applications.
