1 From a raw material to an end product System solutions for natural fiber-reinforced plastics Engineering Value

2 Numerous applications Overview of natural fiber-reinforced plastics Decking profiles Fence components Window profile with core of WPC and recycled PO

3 3 Siding profiles Decking profiles for terrace coverings Natural fiber composites are an ideal substitute for pure natural products in many application areas, thanks to their durability, for example. Decking products such as floor coverings for terraces, but also fence components, screen walls or door frame profiles are some of the products that are already made of Wood Plastic Composites (WPC).

5 5 Natural fiber-reinforced plastics Innovative system solutions from KraussMaffei Berstorff We are your contact for developments in processing composites with renewable raw materials. In addition to wood, the most important renewable raw material, different fibrous materials such as hemp, flax, rice husks, cellulose, etc. can be processed with a large number of polymers (e.g. HDPE, PP, PVC) in different mixtures to form a composite. KraussMaffei Berstorff covers the entire value-adding chain with its product portfolio of co-rotating and counter-rotating technology for extruding composites made of renewable raw materials. Starting with the selection of the suitable raw material and the formulation, material processing and pelletizing through to extrusion and production of complete application systems, KraussMaffei Berstorff is a system supplier who can realize individual requests from customers for the extrusion of natural fiber composites. Your advantages: Energy-efficient production thanks to innovative machine technology Maximum flexibility in processing different formulations Perfect product quality over a defined performance range with homogeneous profile surfaces Optimization of the formulation through professional advice Active wear resistance thanks to a bi-metal processing unit with counterrotating extruders coupled with tungsten carbide protection Innovative system solutions to maximize customer utility Partnership when developing new applications Turnkey project management by KraussMaffei Berstorff's specialists ECOLIFE window profile with a core made of a mixture of wood flour and recycled PO and a premium quality outer coating of HDPE with an aluminum protective layer. The processor benefits from the two-stage process; he can compound the material using KraussMaffei Berstorff machines and also extrude the corresponding end product in the downstream production step.

6 6 Natural fiber-reinforced plastics Extrusion systems Co-rotating twin-screw extruders Counter-rotating, parallel twin-screw extruders System solutions for natural fiber-reinforced plastics High-performance extrusion systems Counter-rotating twin-screw extruders for processing compounds Counter-rotating twin-screw extruders are used all over the world to process natural fiber-reinforced plastics, for example Wood Fiber Composites. The KraussMaffei Berstorff extruders in the 32D series are characterized by a large number of advantages, for example constant material feed, careful material preparation and high pressure stability of the screws when manufacturing semifinished products. They are also ideally suited for processing of a prepared compound. High screw torque coupled with a long processing unit produces the highest possible output rates. In addition to careful material preparation, the special screw geometry produces a homogeneous melt with an optimum mass temperature even with high melt pressures. Active wear resistance for long service lives KraussMaffei Berstorff ensures maximum wear resistance through a special process concept, tungsten carbide protection of the screws and bi-metal lining of the barrel bores. The machines require minimal maintenance and have long service lives which, depending on the formulation and specification-based operation of the machines, can amount to between 12,000 and 20,000 operating hours. Coextrusion: The economical option Coextrusion is also increasingly becoming a trend in NFC processing. For example, the core of a profile can be made of natural fiber composites while the outer layer is made of PVC or PO. However, both the core and outer layer may be made of natural fiber composites. Co-rotating twin-screw extruder for cost-effective compounding Thanks to the concept of the co-rotating twin-screw extruder, the components can be directly metered on the extruder in an energetic and economically efficient way through direct extrusion. The use of patented multi-processor screw elements ensures careful material preparation and homogeneous mixing of the natural fibers. Other advantages include the long service life of the inductively hardened housings and extremely flexible adaptation to different processing requirements due to the modular design of the processing element.
