42| PLASTICS ENGINEERING | OCTOBER 2011 | www.4spe.orgplastic polyurethanes (TPUs) used byNanoflex. The founder and presidentof Nanoflex, John Filipelli, a formerhorse trainer, says that his firstattempt to develop an alternative tometal horseshoes "was to develop apolymer boot, not a horseshoe .The boot didn't work and it was for-tuitous that I [met] Roger Huarng, aformer BASF technical materialsexpert and now a principal withAPS." "Together," Nanoflex says,"the two agreed on a proprietarygrade of polyurethane that had allthe attributes required for the appli-cation-consistency and uniformdensity across the shoe, toughness,durability, a certain level of flexibilityor cushioning and at a cost compara-ble to a metal horseshoe. The eques-trian products are made entirely ofpolyurethane based on nanotechnol-ogy, no metal." Other reported bene-fits include: the shoes can be appliedin either traditional way-with nailsor with Equalox or Vettec, popularadhesives used for securing horse-shoes; the horseshoes stay on longerthan traditional metal shoes; thedurability of the polyurethane iscomparable to that of aluminumhorseshoes; one size, when trimmed,fits any horse; and the polymer shoesare reversible, which can result ineven longer life. Nanoflex says that to both confirmproduct claims and answer industryskepticism, the company conductsongoing research to verify that poly-mer horseshoes are viable alternativesto those made of metal. Among theresults, the company says, are lame-ness prevention, increased circula-tion, improved traction, increasedcomfort, and improved gait andfaster running speeds. Cable Components Group(CCG), Pawcatuck, Connecticut,USA, has introduced a new fluori-nated ethylene propylene(FEP)-based pellet in a concentratedmasterbatch to chemically foam insu-lations for plenum cable applications.The FluoroFoam pellets are a UL-recognized component for plenumcable insulation (QMTM2), thecompany says.CCG says, "The product is espe-cially suited for thin-wall insulationof 0.006 inch (0.152 mm) to 0.010inch (0.254 mm) for Category 5e, 6and 6A. Unlike competitive productsthat foam FEP, it does not requirethe complexity of gas injection extru-sion lines to foam FEP. Therefore,standard high-temperature extrudersenable the chemical foaming at 35%,45%, or 55% based on a designatedproportional use of the FluoroFoammasterbatch and FEP."Enhanced electrical performanceand lowering material content arealso benefits of this patented technol-ogy, CCG adds. In July 2011, CCGreceived both U.S. Patent 7,968,613and European Patent 2176326B1 forits FluoroFoam line of chemicallyfoamable pellets and cable fillers. Thefoaming technology patent coverageincludes perfluoroalkoxy copolymerand tetrafluoroethylene perfluo-romethylvinylether copolymer, aswell as In late July, RheTech, Inc.,Whitmore Lake, Michigan, USA,announced that it has launched anew product line of biocompositematerials called RheVision. A "sus-tainable alternative to traditionalmineral- or glass-reinforcedpolypropylene," the company says,"RheVision uses bio-fibers fromwaste materials (initially wood fiber,rice hulls and flax fiber) to producematerials that have a wide range ofapplication in automotive, consumerand construction markets.""RheVision was developed toaddress the growing demand fromcustomers and consumers for moresustainable materials," said RheTechexecutive vice president AndrewHopkins. "This new biocompositeproduct line balances performance,competitive economics and environ-mental benefits. RheVisionproductshave a substantially lower carbonfootprint than traditional reinforcedpolypropylenes and, in addition tosavings in landfill cost and space, arelighter weight than traditional rein-forced polypropylene compounds.They are easily moldable and extrud-able with standard equipment andcan easily be colored with standardcolorants."The company adds that futureRheVision products are under devel-opment, utilizing other natural rein-forcements and incorporating signifi-cant levels of post-consumer recycledmaterial. RheVision technology wasdeveloped at the company's Technicaland Application Center in WhitmoreLake. Privately held RheTech hasthree plants in Michigan and Ohio.industryNEWS and NOTESCONTINUEDRudolph D. Deanin1921-2011Dr. Rudolph D.
