Polyetherimide examples of properties

General chemical properties are subject to the compatibility of the fillers and reinforcements with the ambient conditions. If the fillers are well adapted, the chemical properties are the same for filled and neat polymers. 

Weak acids Strong acids Bases Solvents 

Good behaviour with dilute acids Good behaviour limited to pH 9 

PEI resists mineral acids, dilute bases (pH less than 9), freons, oils, greases, gasoline, most fuels, certain hydrocarbons and fully halogenated hydrocarbons, most cooking oils and greases, most detergents and disinfectants 

They are attacked by certain hydrocarbons, partially chlorinated solvents, ketones Possible for special grades
