SUMIKAEXCEL 4800P
Grade Information
SUMIKAEXCEL 4800P is a powder grade of polyethersulfone (PESU) designed to be dissolved or dispersed in solution. The grade name is related to the molecular weight, and 4800P has an intermediate molecular weight. There is a correlation between molecular weight and solution viscosity.
SUMIKAEXCEL PES has excellent toughness, high heat resistance, high dimensional stability, hydrolysis resistance, and chemical resistance. It is also transparent, has long-term heat stability, excellent metal adhesion, moldability, and inherent flame retardancy.
