SUMIKAEXCEL PES is a transparent resin with a slightly amber color. It possesses a variety of useful properties, such as heat resistance, creep resistance, dimensional stability, flame resistance and hot water resistance. SUMIKAEXCEL PES is utilized as a molding material in many different applications including automotive parts, electronic components or sterile medical and dental instruments.  SUMIKAEXCEL powder grades are utilized as impact modifier for epoxy-based composites used in aircraft, heat resistant coatings, adhesives and membranes used in the medical and other industries. Sumitomo Chemical is the only manufacturer with a dedicated PES polymerization facility. Sumitomo Chemical PolyEtherSulfone is therefore free of any cross-contaminating products.
