LEAFLET Special kneading barrel The Japan Steel Works, Ltd. Plastics Machinery Business Division NIC (Nikko Intensive Cylinder) is a barrel with flow direction grooves on the inner surface to pass more polymer through the gap between grooves and screw tip. With the extensional polymer flow, NIC improves mixing and dispersion performance with lower polymer temperature which cannot be attained only by screw configuration. Applicable process 1. Polymer blending (e.g. ABS+AS, PP+EPR, etc.) Fig. 2 Kneading effect at tip clearance 2. Filler compounding (e.g. talc, calcium carbonate, magnesium hydroxide, etc.) Performance evaluation 3. Master batch compounding (e. g. Carbon black, titanium oxide, etc.) 4. Other compounding with high-level micro dispersion Features 1. Higher mixing performance ・Extensional polymer flow between grooves and screw tip increases kneading effect. ・Mixing temperature can be reduced as average shear rate decreases. 2. Energy saving ・10 to 20 % lower energy consumption than standard barrel. 3. Less polymer stagnation ・Mixing at high viscosity area prevents localized heating and black specks. Japan Steel Works, Ltd.
