We take an objective look at the types of polymer fillers and reinforcements available and which ones will give you the results you’re seeking. There are quite a few options in the mineral family, and they not only reduce cost, they can also boost strength when added to a polymer. It’s a relatively inexpensive material, one that's widely used at large percentages to reduce the cost of a compound.
