Mechanical recycling of postused highdensity polyethylene crates ...14 Jun 1999 ... Abstract. A remeltingrestabilization technique was applied for the recycling of postused, yellow-pigmented high-density polyethylene (HDPE) bottle crates. Multiple extrusion cycles procedure, at different reprocessing temperatures, was performed for monitoring the processing stability of the restabilized and nonrestabilized material as reference. In addition, mechanical properties measurements were carried out, to study further the effect of restabilization on the&nbsp;...

Tropical Timbers of the WorldWeight. Specific gravity or density may be related to important wood attributes such as mechanical strength, shrinkage, paper-forming properties, and cutting forces required in machining. Often in assessing the use potential of a species, specific gravity is a characteristic that receives first attention. Basic specific gravity is the ratio of wood density to the density of water at 4° C and is calculated from the ovendry weight and volume in the green condition. This may range from less than 0.1.
