    Abstract: Compounding or extrusion rates can be increased by splitting the polymer solid feed. Melting of additional solid polymer is significantly assisted by excess enthalpy from incoming melt from a primary mixing stage. Depending on resin rheology and melting characteristics, rate increases were achieved of from up to about 55 to about 100% rate increase over the use of a single feed at the same rotor speed. The net result is a decrease in the overall SEI (specific energy input to the polymer) and thus melt temperatures.
