Using Polyetherimide Thermoplastic for Forward Lighting Complex Reflectors

This paper will discuss the analysis of a high-heat, unfilled polyetherimide (PEI) thermoplastic in a complex reflector application with conventional aim (bubble-vial) beam pattern. The advantages and disadvantages of using PEI thermoplastic vs. bulk molding compound (BMC) in a complex reflector will be presented. Design features, testing methodology, and processing techniques for the use of PEI in such applications will also be highlighted.
