Definitions

  • the plastic cells and the GRM infill dynamically support each other and should be able to survive under a wide spectrum of loads, vibrations, impact loads, thermal stresses and erosion.
  • the at least one layer may provide at least 10% greater thermal conductivity relative to a layer of HDPE having the same dimensions.
  • polymer or oligomer chain i.e., a polymer or oligomer modified by an average of at least one reactive group per chain.
  • the functional group containing polymer or oligomer is a modified polyolefin, ethylene copolymer or ethylene terpolymer, wherein the functional group is grafted to the polymer or oligomer.
  • This may be formed in situ, or prior to melt kneading with ET, by functionalizing the PO in which case it is a self compatibilizer, or may be added as an ingredient, e.g., to the extruder together with ET and any un-functionalized PO, in which case it is an external compatibilizer.
  • polyurethanes suitable for the present disclosure are PellethaneTM, manufactured by DOW, EstaneTM and TecothaneTM, manufactured by Noveon and DesmopanTM, manufactured by Bayer.
  • the term 'compatibilized' refers hereinafter to a stable dispersion of one polymer in another polymer, wherein, due to limited compatibility in the solidified state, the two polymers are immiscible one in each other and tend to phase- separation during crystallization and solidification, in the absence of the compatibilization as described herein.
  • a compatibilized blend as defined in any of the above is provided by melt kneading of the ET and PO phases and a compatibilizer selected either from one or more external compatibilizer, self compatibilizer or a mixture thereof.
  • the CTE of an article formed of the compatibilized blend of the present disclosure is lower than about 125 ppm/°C.
  • the filler includes one or more of calcium carbonate, talc, dolomite, silica, clay, wollastonite, Atty Docket No. PRSI 2 00004 PCT
  • Retention means final ETB divided by initial ETB.
  • the UV and heat stabilized compatibilized blend is more resistant against UV light and thermal induced degradation relative to HDPE including the same dosage of the same additives.
  • the mechanism behind this feature is the slower leaching and/or evaporation rate, relative to HDPE, of the UV absorbers and light stabilizers from the polymeric article by humidity and heat, the slower diffusion of free radical due to increased barrier properties and the lower heat buildup in the layer due to improved heat conductivity.
  • the leaching rate is slower due to the inherent barrier properties of engineering thermoplastic, especially polyamides and polyesters, and the Atty Docket No. PRSI 2 00004 PCT
  • the geotechnical article includes friction-promoting features on at least one outer surface of the article, wherein the friction-promoting features include, for example, texture, embossment, debossment, through-hole, finger-like extension, hair-like extension, wave-like extension, co-extruded line, bonded fibers or grains or aggregate, dots, matte or any combination thereof.
  • the geotechnical article is a three dimensional cellular confinement system (CCS) including a plurality of the strips, each of the strips communicating with its neighboring in a side by side relationship via discrete physical joints, in which the joints are spaced one from the other by non-joined areas.
  • the three dimensional CCS is adapted for containment and/or confinement and/or reinforcement of earthen material, soil, rock, gravel, sand, stone, peat, clay, concrete, aggregate, road building materials and any combination of two or more thereof.
  • the ultimate weld strength of two welded strips at plus 70 0 C is greater than about 1000 N for a weld width of 100 mm.
  • Fig. 4 is a perspective view of a single cell 20 of a CCS, formed of or including a compatibilized polymeric composition, including a tendon 12, in accordance with another embodiment of the present disclosure.
  • the tendon 12 passes through the walls 14 at the apertures 34.
  • the tendon 34 is used to help maintain the CCS in its intended location, particularly in those applications wherein wedges are forbidden or cannot be used due to limitations imposed by the substrate.
  • tendons may be used in an application where the CCS is placed on a geomembrane, and it is desired to not penetrate the geomembrane with a wedge.
  • the tendon 34 Atty Docket No. PRSI 2 00004 PCT
  • the reinforced wall portion 40 may be used instead of the locker 38. That is, reinforced wall portion 40 may include an aperture 34, through which a tendon 12 may pass. In another embodiment, a combination of a locker 38 and a reinforced wall portion 40 may be employed with a tendon 12. Such may be used, for example, where an especially high stress is expected to be applied to the wall of the CCS during use.
