Grade Line-up for SUMIKAEXCEL PES

Molding Grades

There are two grade categories for injection molding which are non-reinforced grades and glass fiber reinforced grades.

General Purpose Grades
3600G - High-flow grade for injection molding
4100G - Standard grade for injection and extrusion molding
4800G - High molecular weight grade for injection and ectrusion molding
3601GL20 GF20% High-flow grade for injection molding
3601GL30 GF30% High-flow grade for injection molding
4101GL20 GF20% Standard grade for injection molding

Powder Grades

A variety of grades are available as powder grades having different RV values (reduced viscosity), which is a guideline for molecular weight.
The most appropriate grade may be selected to suit the particular application.
The following solvents can be used with SUMIKAEXCEL PES : N-methylpyrrolidone (NMP), dimethylformamide (DMF) dimethyl acetamid, utyrolactone, and a 50 / 50 (weight %) mixture of dichloromethane and 1,1,2 trichloroethane.
