plastic composites. A better reinforcement is achieved by using wood fibers with a higher aspect ratio, but individual fibers are seldom used in composite manufacturing due to processing problems and higher cost. Therefore, the objective of the first part of this work was to study the The study showed that wood chips can be used as material in a one-step process for manufacturing (TPW 113, supplied by Struktol, USA) was used as processing aid and an antioxidant agent.
The wood used to manufacture these composites is mostly in the form of wood flour (typically 40 mesh or lower) or recycled paper fiber. wood contents typically range from 20 to 60% in these composites. Additives to the composites will include processing aids (lubricants, antioxidants, acid scavengers), and property enhancers (biocides, coupling agents, inorganic fillers, fire retardants, uv stabilzers, colorants, etc). processing Unit Operations. The unit operations for extruding wpc

5 Dec 2000 Introduction. In this presentation we will discuss the use of additives such as lubricants, rheology modifiers and dispersion aids in wood-filled PVC composites. It is the goal of this paper to show improvements in flow, surface appearance, process stability and overall processing characteristics of the composite. It is also the goal of the paper to illustrate that these process improvements are conducive to achieving higher filler loading levels without sacrificing
Struktol expertise is not limited to processing aids only. They have the technology to formulate ingredients to obtain higher performance, next generation materials. These projects are handled with complete client propriety. PICTURED BELOW: The following picture illustrates how the additions of Struktol lubricants change the surface qualities of a polymer composite almost immediately. Regardless of your polymer, or type of wood or natural fiber being used, Struktol has a Engineered
The advent of formaldehyde emissions controls has led to the use of binder resins that have made the role of the release agent in the wood composite/panel pressing industry more important. A good example is pMDI, which may prove more difficult to release than “traditional” binders and has been known to increase the rate of build-up on pressing surfaces. pMDI systems can be quite difficult to process, as the composite

wood Polymer composites. wood-Polymer composites (WPC's) are thermoplastic compounds containing wood fiber or wood flour typically in polymers such as PE, PP or PVC. The amount of wood in the composite can range from 30 - 70%, although 40 - 50% is more common. wood-polymer composites can contain a variety of other additives such as coupling agents, process aids, antioxidants, mineral fillers, and pigments. The advantage of wood-polymer composites is they can be
Lubricants / Process aids. Our range of lubricants for wood plastics composites can be incorporated directly during the extrusion process to give the following benefits: Increased throughput; Improved flow; Superior dispersion; Reduced processing temperatures and pressures; Reduced wear on processing equipment; Enhanced We were approached by a wood plastic composite (WPC) producer who had been experiencing difficulties during manufacture of extruded deck-boards.
Today, at least 50 companies offer composite products of wood-reinforced polyethylene (PE), polypropylene (PP) or polyvinyl chloride (PVC) for decks, docks, door and window trim (both interior and exterior) and automotive interiors. . "Typical additives in wood flour/polymer formulations include processing aids like lubricants, antioxidants and acid scavengers and property enhancers, like biocides, coupling agents, inorganic fillers, fire retardants, UV stabilizers and pigments," says
Chem-Trend's decades of experience in the field helping companies produce parts through a variety of different processes have lead it to develop a broad portfolio of manufacturing process aids. Today's wood fiber pressing mills face increasing challenges due to a changing regulatory and market environment. Chem-Trend works continuously to develop new technologies to help panel and engineered wood product producers address those challenges. Read More ». Want to find
especially regarding effects of the wood component. Manufacturing processes are also significant contributors to the suitability of WPCs for a given use, and the impact of various aspects of manufacturing are discussed as well. The environ- . The wood component can be of any shape or size and acts as a filler and/or reinforcement to the composite. Making up a relatively small proportion of the total composite are additives which are added to aid in processing and affect a variety
