Glass fibers are commonly added to nylon, polypropylene and other polymers to make glass-fiber reinforced plastic (GFRP) that is stiffer and stronger than unfilled polymer. Use an extruder feed throat that is 2 feet 6 inches long or longer to avoid bridging, and use general purpose metering screws (not mixing screws) with deep flights. The iron oxides magnetite and hematite are used to add density to such plastics as polypropylene, polyamides (nylons) and polyethylene, giving them the weight of metal but the versatility of plastic.
