Influence of nucleating agent type on the morphology of extruded polyetherimide foam for printed circuit boards*

Abstract: This work focuses on the development of foamed high temperature thermoplastic substrates for printed circuit boards. For this application it is necessary to achieve mean cell diameters smaller than 30 µm in order to be able to realize vias and high packaging densities (miniaturization). Different additives as nucleating agents, namely macro- and micro-crystalline talc, silica, calcium carbonate, and wollastonite, were melt-compounded with polyetherimide using a twin-screw extruder. Foamed samples are prepared … Show more

“…Moreover, the hydrogen bonding that formed between the C = O with N-H groups are prone to form strong inter-chain interaction, resulting in the decrease of molecular movement and enhancement of melt viscosity of NPEAO precursor during the foaming process. 33,34 As the result, the foaming degree of NPEAO powders sharply decreased with increasing the BIA content.…”
