SUMIKAEXCEL 2603MP
Grade Information
SUMIKAEXCEL 2603MP is a micropowder grade of polyethersulfone (PESU) modified with hydroxyl end groups. It is primarily used to dissolve or disperse in thermosetting resins such as epoxy resins.
The grade names are related to the molecular weight, and SUMIKAEXCEL 2603MS has the lowest molecular weight among the MP series with hydroxyl end groups. There is also a correlation between molecular weight and solution viscosity.
