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 【Get Price】

28 jul 2010 greenscapes website1, in fact, appears to wholeheartedly endorse plastic lumber over traditional materials for a wide variety of applications. but is sweeping endorsement justified? is everything that is being said, in fact, true? a bit of investigation into wpc performance to date suggests that caution may be in order when considering such products. for instance, various sources document a number of problems that have been encountered with plastic composite.【Get Price】

reasons to avoid wood/plastic composite decking and profiles trade

he had 120 sq metres of wood plastic composite decking laid at his home. unfortunately, water had been absorbed by the wood component of the composite decking, and when the sun came out, the whole deck began to warp. 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. this particular of warping in composite wood plastic decking was not covered by 【Get Price】

wood-plastics composites done right : plastics technology

26 apr 2012 entek extruders. wood-plastic composite (wpc) products were first widely marketed in the early 1990s as weather-resistant decking. adding wood to plastic to make wpc reduces the formula cost, raises the modulus of elasticity, and lowers the coefficient of thermal expansion. common wpc quality problems arising from thermal degradation of wood are distortions in the extruded profile, known in the industry as “dog-boning,” “swelling,” and “ridging.” figure 3 【Get Price】

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 sagging problems, espe- cially in a warm environment. on the other hand, this flexibility can be an advantage: wpc can be bent on-site to make attractive patterns. wpc is touted as having envi- ronmental benefits, because it is made from residues (wood) or re- cycled materials (plastic).【Get Price】

considerations in recycling of wood-plastic composites treesearch

now that wood-plastic composites have become a major player in the north american decking market, many of the lessons learned in how treated-wood decking has historically been used, removed from service, and then discarded or recycled may help the wood-plastic composites industry and the recycling industry prepare for their future materials and their needs. this paper will discuss the materials and process issues of wood- plastic composites related to future recycling efforts.【Get Price】

(tdca), although these appear to be limited to a particular type of 'cheaper' hollow form board. installation errors were a feature in many cases, although product quality issues remain under question. concern has also arisen about new deck boards being fitted over existing substructures which are often unsuitable for wood plastic composite. the tdca therefore 【Get Price】

4 jun 2015 the most abundant profiles made from wood–plastic 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 【Get Price】
