NPE2012 news wrap-up MATERIALS AT NPE All Market Sectors Benefit From Large Crop of New Materials Higher-performance and easier processing PE film resins for packaging, a one-pass crosslinked PE for photovoltaic (PV) wire and cable, several higher-performing nylons and TPEs, "greener" plas- tics, and enhanced styrenic and PC resins are among the new mate- rials that made their debut at the big show in Orlando, Fla., last month. About 50 new resins and compounds were launched for packaging, automotive, electronics, building /construction, medical, sporting goods, and other consumer and industrial applications. NEW POLYOLEFINS FOR FILM, WIRE & MORE Dow Chemical Co. (dow.com), introduced Elite Advanced Tech- nology (AT) PE resins to meet growing demand for higher-per- formance films, particularly for sealant, stretch-wrap, and stretch-hood film for food other consumer and industrial pack- aging. Based on patent-pending "post-metallocene" technology, it is made with a non-metallocene, single-site catalyst. Resulting materials are said to offer consistent, high-performance seal properties along with advantages in optics, stiffness, toughness, processability, and organoleptics, making them well suited to a wide variety of vertical-form and horizontal form-fill-seal appli- cations. They also resist gas fading in tough warehouse environ- ments. There are three initial offerings: r" CMPXO àMN TFBMBOU HSBEF UIBU IBT NFUBMMPDFOF QSPQFSUJFT and the performance of LLDPE but with faster processing; r" TUSFUDI IPPE àMN HSBEF BT B SFQMBDFNFOU GPS &7" CPBTU- ing good dart impact, puncture, and tear resistance; r" TUSFUDI XSBQ DBTU àMN HSBEF GPS IJHI TQFFE BQQMJDBUJPOT that boasts much better toughness, less leftover unsaturation, good drawability, and 20-25% higher extensibility than metal- locene resins. Next up: new shrink and barrier film grades. Dow also added new Sealution 210 to its Sealution Peel Poly- mers, a line of ready-to-use, single-pellet olefinic formulations for easy-open packaging made from polyolefin blown and cast films. It boasts higher clarity for packaging such as fresh-cut produce wrap, clear tops for PP dairy cups, and microwavable stand-up pouches. It supplements earlier grades, such as Sealu- tion 140 (launched at K 2010 in Germany), which had lower clarity for applications such as cereal bags. PolyOne Corp.

Thermylene P9 is a short-glass reinforced grade described as a "nylon alternative" due to its enhanced temperature resistance. Applications include auto air-intake manifolds and other under- hood parts. Due to its low specific gravity, it can enable weight reduction of 15% or more.
