Outdoor durability of wood-polymer composites oxidation, and rain. wood is hygroscopic, readily absorbing moisture due to the prevalence of hydroxyl groups. All wood components are also susceptible to degradation by uv radiation.
Dimensional stability and flexural properties of the WPC were degraded after 12 accelerated FT cycles as well as 2000 h of uv weathering for both recycled and virgin. HDPE and PP based composites. However, the MAPP coupled
What is Novowood, works, costs, materials, advantages of using composite wood WPC. Is Plastic wood uv-rays resistant? Novowood resists the uv rays damage thanks to a special composition of pigments and uv absorbers.

15 Oct 2016 Both parameters are appropriate indicators to describe the ageing of WPC cladding. Weathering of WPC decreases MOE more than MOR. Exposure to uv-radiation is more harmful than frost-thaw cycling. In order to minimize
polymer composites were used as the outer layer, making them exposed to ultra violet exposure, hence prone to uv radiation. ..  have investigated the effect of uv radiation to wood plastic composite. Here, a fluorescent lamp with peak
Material degradation of WPC is primary caused by fungi, uv-radiation and freeze–thaw. ?. The total strength decrease of WPC under these impacts makes up to 50%. ?. A realistic WPC-cladding design value shows similar extent to comparable
23 Jul 2016 Weathering of WPC resulted in a surface lightening and a decrease in wood index (wood/HDPE) and flexural strength. WPCs that uv radiation degrades the WPCs surface, further causing it to become cracked and flaky.
uv has been used as initiator to replace ionizing radiation for certain experiments. The additives used were S. Elvy, G. Dennis, L.-T. NgEffects of coupling agent on the physical properties of wood-polymer composites. J. Mater. Process.
