  • Benefits of composite decking and maintenance free decking Plastic is typically softer than wood or wood-composites, and is susceptible to expansion and contraction from variable temperatures. To compensate for the decreased strength of recycled plastic lumber made from 100% HDPE, Bear Board manufactures its lumber using at least 50% recycled content and mixes the plastic..

  • Experimental investigation on mechanical properties of extruded . tages of both plastic and wood wastes in producing a new class of materials [13]. Moreover, they can be reproc- essed to produce recycled products with acceptable prop- erties [4, 5]. The physical and mechanical properties of multiple recycled composites have been investigated and, even in some cases, the strength was..

  • Composite or PVC: Which One is Best?| EcoBuilding Pulse . But then try asking them to explain what makes one brand's wood-plastic composite (WPC) or polyvinyl chloride (PVC) decking or trim different from another. .. Though virtually all industry experts agree that composite and PVC decking and trim is far better than it was just a few years ago, they stress that variations between..

  • Thermal and Dynamic-mechanical Properties of Wood-PVC . Interfacial bonding strength increased with the increase of E' and E* at low MAPP retention, but was not so sensitive to these moduli at high retention levels. Compared with PVC, wood, and wood-PVC composites without MAPP, maleated wood-PVC composites had significant shifts in most DMA, TGA, and DSC spectra

  • Composite Decking 101 - Bob Vila CONS OF COMPOSITE DECKING. Strength and Weight. Though comparatively heavier in weight, composite decking tends to be slightly less strong than its wood cousin, so a deck built from composite components must have additional supports. It Can Stain. Plastic is largely responsible for many of the positive features that..

  • PVC Decking | ProSales Online | Composite Materials, Decks, Wood . Feb 2, 2009 . PVC boards owe most of their strength to the fact that they lack wood fibers, the culprit behind many of composite's weaknesses, such as staining, fading, and mold growth. "Some of the differences with our PVC products is that we have a glass fiber in there, and we don't have an organic filler," says Adam..

  • Mechanical properties of poly (vinyl chloride)/wood flour/glass fiber . Short glass fibers were added to poly(viny1 chloride) (PVC)/wood flour composites as reinforcement agents. Unnotched and notched impact strength of PVC/wood flour/glass fiber hybrid composites could be increased significantly without losing flexural properties by adding type L glass fibers and over 40% of WC

  • Patent EP1940608A1 - Pvc/wood composite - Google Patents Jul 9, 2008 . The present invention relates to a thermoplastic/natural cellulosic fiber composite, and more specifically to a high molecular weight compatibilizer within that composite resulting in both a high flex strength and high modulus and significant reduction in water absorption. The compatibilizer is preferably a..
