2. Wood–plastic composite - Wikipedia

   en.wikipedia.org/wiki/Wood–plastic_composite

   Wood-plastic composite. Wood–plastic composites (WPCs) are composite materials made of wood fiber/wood flour and thermoplastic(s) such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), or polylactic acid (PLA). In addition to wood fiber and plastic, WPCs can also contain other ligno-cellulosic and/or inorganic filler materials.

   Cyclic olefin copolymers are produced by chain copolymerization of cyclic monomers such as 8,9,10-trinorborn-2-ene or 1,2,3,4,4a,5,8,8a-octahydro-1,4:5,8-dimethanonaphthalene (tetracyclododecene) with ethene (such as Polyplastics subsidiary TOPAS Advanced Polymers' TOPAS, Mitsui Chemical's APEL), or by ring-opening metathesis polymerization of ...

5. Plastic lumber - Wikipedia

   en.wikipedia.org/wiki/Plastic_lumber

   Even with a wood grain design, plastic lumber is still easy to distinguish visually from natural timber: the grains are the same uniform color as the rest of the material. Manufacturers claim plastic lumber is more environmentally-friendly and requires less maintenance than wood/plastic composites or rot-resistant wood. [2]

   A bare, cylindrical vial GTLS constructed of 0.1 mm thick glass that is 10 mm long and 0.5 mm in diameter will yield a surface dose rate of 100 millirads per hour per curie. If the same vial were instead constructed of 1 mm thick glass and enclosed in a plastic covering that is 2–3 mm thick, the GTLS will yield a surface dose rate of 1 ...
