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.

Processing Properties of Wood-Filled PVC - Struktol

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&nbsp;

Mold Release Agents & Process Aids for Binding Agents & Resins

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&nbsp;

Wood Composites - Modern Dispersions, Inc.

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&nbsp;
