File instrumentation will be suitable for processing and preparing any type of polymeric materials based on thermoplastics and thermoplastic elastomers, and mixtures thereof, as well as composites and nanocomposites, powdered ceramic materials bonded with the polymer matrix, with an appropriate melt index.
Melt index is a common measure of how a plastic resin flows during processing and may perform in real world manufacturing.
This work also includes investigation of other polymer design variables, including higher melt index versions optimized for very high flow TPO compounds.
