A filler is a material that can be added to a polymer for injection molding, to improve the quality of the part.
Fillers are added to polymers to alter the properties of the plastic. Fillers can be added to increase the strength, affect the cost, and alter the brittleness of the part.
Autodesk Simulation Moldflow provides a filler database from which you can select a variety of fillers.
You can look at the properties of various fillers in order to select the most appropriate for your simulation.
This dialog is used to view the properties of the filler you have chosen.
