The electrical job
Insulating, dissipative and conductive requirements differ.
Electrical function needs its own specification. A polymer name, filler or color cannot establish the finished part's electrical performance, and an insulating material is not automatically a static-control material.
Use the exact grade on the drawing
The ULTEM and PEEK pages explain general machining and grade considerations. Your engineering team selects the material; neither family name identifies an electrical or static-control grade.
Keep material and system requirements separate
Dielectric, ESD and flame requirements have different test scopes. State the specified grade and acceptance criteria for the part. CDS must confirm any requested records or tests; a material classification does not establish an ESD program or finished-part conformity.
