Using Coperion’s ZSK twin screw extruders to produce hot melt adhesives allows the use of a wide range of different recipe components and ensures consistently high product quality without batch-to-batch variations. The ZSK twin screw extruder in modular design and individually configured to the product group combines various process steps in one machine: plasticizing/masticating, mixing, homogenization, venting and devolatilization. By using special equipment, even non free flowing raw materials (e.g. rubber bales) can be fed into the continuous process in a controlled manner. Large volumes of resins and/or softeners can be incorporated speck-free e.g. by splitting the volumes in partial currents. Entrained air, moisture and volantiles are reliable removed from the product flow by applying vacuum.
