SUMIKAEXCEL 2603MPS

Grade Information

SUMIKAEXCEL 2603MPS is a micropowder grade of polyethersulfone (PESU) modified with hydroxyl end groups, designed to be dissolved or dispersed in solution.

The grade names are related to the molecular weight, and SUMIKAEXCEL 2603MPS has the lowest molecular weight among the MPS series. There is also a correlation between molecular weight and solution viscosity.
