Composite Materials from Plastics and Biofibers
Cincinnati Milacron Extrusion Systems, Batavia, Illinois/USA, introduced its new "FibrePlast" system at the K2010 trade show. It represents the company’s second generation of extruders designed for the processing of wood and biofiber plastics composites. FibrePlast extruders can process agglomerates based on PP, HDPE and PVC, and/or recycled plastics. They are available at two different sizes, with maximum output rates up to 2,280 kg/h (based on an average ratio of 50 % PP and 50 % wood dust). The system employs a special technique to mix the materials at high intensity, thus generating ready-to-use materials, when cooled down. When mixing composite materials on a polyolefine basis, the system steps up the bulk density of the particles in order to make material feeding more homogeneous, thus providing for the finished product to serve as a basic material for downstream processing. The consistency of PVC-based compounds is very similar to a dry powder mixture.
The extruder reduces the humidity content of the fiber from 12 % to approx. 1 %, while at the same time making sure the fiber content and all additives mix homogeneously. This direct processing includes a significant benefit in terms of costs, because energy-consuming pre-drying is omitted.
Cincinnati Milacron claims to be among the leading producers of extruders designed for the processing of wood and biofiber composites, having sold more than 350 extruders to this market segment over the past 20 years. For WPC processing, a specially modified machine series is applied, consisting of conical and parallel counter-rotating twin-screw extruders.
