Two new modifiers for PP fibers.A pair of specialty modifiers for PP fibers and nonwovens are available from Ciba Specialty Chemicals “Ciba” redirects here. For the pre-1971 company, see Novartis. Ciba Specialty Chemicals is a chemical company based in and near Basel, Switzerland. It was formed as the non-pharmaceuticals elements of Novartis were spun out in 1997, following the merger in the , Tarrytown, N.Y. Irgasurf HL 560 is a hydrophilic hydrophilic /hy·dro·phil·ic/ (-fil´ik) readily absorbing moisture; hygroscopic; having strongly polar groups that readily interact with water. hy·dro·phil·ic adj. additive that gives PP fibers a long-lasting wettable effect. It makes PP nonwovens absorb up to eight times their weight of water. It also adds antistatic properties, reduces friction, and increases the softness and comfort of diapers, adult incontinence pads, and feminine care products. Irgatec CR 76 is a non-peroxide modifier that provides controlled degradation of a low-MFR PP into a high-flow resin with narrow molecular-weight distribution. It allows a spunbond grade of 20 to 35 MFR MFR, n See myofascial release. or recycled fiber scrap to be used in melt-blown applications, which require higher flow. Narrow MWD MWD Metropolitan Water District of Southern California MWD Measurement While Drilling (oil drilling) MWD Morgan Stanley Dean Witter (stock symbol) MWD Molecular Weight Distribution MWD Military Working Dog provides higher tensile strength and elongation. CR-76 is a hindered hydroxylamine hy·drox·yl·a·mine n. A colorless crystalline compound, NH2OH, explosive when heated, that is used as a reducing agent and in organic synthesis. ester in a polymer concentrate. It can also be used to crosslink PE or graft polyolefins via reactive extrusion. Tel: (800) 431-2360 * PT Direct: 983HK [ILLUSTRATION OMITTED] |
