Uses of Polyetherimide Resins

There are two different types of performance needs that must be considered when one is discussing melt-processahle polyetherimides. These two types of performance needs are those of the molders or extruders who fabricate the articles and those of the design engineers and the users of the articles made from the PEI resins. 

The molders or extruders are most interested in the melt processing of the resin. Some of their concerns include 

The other families of users who need to he accommodated when one is developing a polymer (or blend) are the design engineers and end users, the people interested in the performance of the molded part or devices made from it. Their concerns can include the following. 

The answers to these types of questions are often complex, being influenced by part design, molding, polymer type, and exact end-use conditions. 

The concerns of both groups of users have to be accommodated in the molecular structure of the polyetherimides or their blends.
