Wood Decking or Wood Plastic Composite (WPC) Decking ...13 Jan 2012 ... wood that are treated and properly installed will have a much higher life span and durability than an 'untreated' wood. Buyers may get confused by some wpc suppliers, when wpc suppliers compare its product's features against 'untreated' wood while using wood as a general term in the comparison. Untreated wood that is not properly sourced or installed may have a higher tendency to common problems such as cracking, splits, fungi growth, color fadiing. On the ...

WoodPlastic Composite Technology | SpringerLink4 Jun 2015 ... The most abundant profiles made from woodplastic composites are boards or lumber used in outdoor decking applications. Although early wpc products were mainly extruded for profiled sections, nowadays, many injected parts made of wpc are being introduced for various industries, including electrical casings, packaging, daily living supplies, and civil engineering applications. Mold and mildew and color fading of wpcs tend to be the durability issues of prime ...

Wood-Plastic Composite Lumber vs. Wood ... - Dovetail Partners28 Jul 2010 ... DOVETAIL PARTNERS, INC. www.dovetailinc.org. Documented wpc problems include: Mold and mildew development. The same types of mold and mildew that affect solid wood can also develop within wpcs (Ibach 2010). Numerous sources report that mold and mildew in wpcs can lead to unsightly blotchy appearance of surfaces and through the product thickness. Biodeterioration. Morrell et al. (2010) cites over a dozen studies reported between 2000.

Wood-Plastics Composites Done Right : Plastics Technology26 Apr 2012 ... Poorly distributed wood fibers, called wood spots, are a common quality problem when the wood contains excessive fines or when the extruder is too worn to achieve good mixing. Ground wood fiber equilibrates at 8% to 12% moisture by weight, depending on the humidity. Residual water in the extrudate leaving the extrusion die causes swelling of the wpc profile, so it is necessary to remove essentially all of the water in the extrudate before it leaves the die and is ...

Ecodeck : Common Problems in Composite Decking & Their Solutions28 Apr 2016 ... Ecodeck Composite decking is a great alternative to wood decks. Yet, there are issues that can't be avoided. Here are some solutions.

First Generation WPC problems and Non-360 degree completely ...Color fading has been a huge issue. The reason for the fading comes from the wood fiber content. Even when mixed with enough antioxidants and UV stabilizers it will still fade due to the nature of the wood fiber. What's even worst it is the fading level would hardly be the same. Page 19. Page 20. Color difference-many decks were faded with uneven color resulting in some boards being lighter and others getting darker. Page 21. 3. Fungus, Mold , Mildew. This problem really has ...

WPC five major quality problems and their solutionswpc moisture content is too high, wood materials tend to have 16-21% porosity, causing it easy to break, susceptible to microbial contamination damage. The solution is to control and reduce the maximum water content in the wood fiber component, and do not exceed the temperature and speed of production and manufacturing processes necessary. best price composite decking material Antioxidants amount is too low, resulting in plastic sheet susceptible to ...

Life Cycle Assessment of Wood-Plastic Composites (WPC)Though LCA have been established over a long time in different kind of industries (automotive, wood, plastic etc.), scientific work is still needed to define system boundaries and allocation problems in detail. The field of study will focus on those issues in the wood Plastic Composite (wpc) industry. The complexity of wood and plastic production chains has to be considered. wood composites derive from virgin and/or second materials where interesting conflicts (e.g. with bioenergy ...

Wood-Plastic Composites: Weathering Quality Issues : Plastics ...This year saw publication of ASTM D 7032, which sets physical specifications for building-code acceptance of wpc deck boards and guard rails. Ongoing work at ASTM is focused on standards that will expand the use of wood and natural-fiber composites into more sophisticated construction applications. Work in Europe is also addressing issues of aging and weatherability, including the need for tests of water absorption, weight loss, weatherability, aging, color fastness, and ...

Critical Issues in Extrusion Foaming of Plastic - Polymers & Polymer ...Foaming of wood-fiber/ plastic composites (wpc) with a fine-celled structure can offer benefits such as improved ductility and impact strength, lowered material cost, and lowered weight, which can improve their utility in many applications. However, foaming of wpc is still a poorly understood art. This paper presents a review of material published, which address the various critical issues particularly in extrusion foaming of wpc, and the proposed processing techniques and strategies ...

Wood Plastic Composites - A Primer - University of Tennessee ...the surface of the composite. wpcs are also usually quite heavy and not as stiff as solid wood. This limits the potential use of wpcs in many structural appli- cations and creates the potential creep or saggin

Advances and Challenges of Wood Polymer CompositesAdvances and Challenges of wood Polymer Composites. Roger M. Rowell. USDA, Forest Service, Forest Products Laboratory and Biological Systems Engineering,. University of Wisconsin, Madison, WI. ABSTRACT. wood flour and fiber have been blended with thermoplastic such as polyethylene, polypropylene, polylactic acid and polyvinyl chloride to form wood plastic composites (wpc). wpcs have seen a large growth in the United States in recent years mainly in the residential.

Reasons to Avoid Wood/Plastic Composite Decking and Profiles Tradewood-Plastic Composite planks and decking are said to have excellent resistance to rot, and are frequently guaranteed for 25 years or more. To look at and feel, ... He was concerned that all similar decking would have the same problems, and asked if our 100% recycled plastic product would perform any better, which of course it does. ... "It seems clear that the marketing of wpc (wood Plastic Composite) products was over ambitious in its rot free claims, and low maintenance.
