Characterization of medium and high flow series 1500 LARC-TPI

H. D. Burks, T. L. St. Clair, Carol R. Gautreaux

Abstract

An imidized version of LARC-TPI was developed on NASA's request for use by both aerospace and electronic industries. Two batches of LARC-TPI 1500 Series, consisting of medium-flow and high-flow pellets with different inherent viscosities, are characterized for their dynamic and isothermal melt flow properties at 340 C, mechanical properties of extrudates, extrudate porosity, and degree of crystallinity. The Series shows significantly better melt flow properties than previosly examimed forms of this polymer.
