NEW VISTAMAXX GRADES FOR SPUNBOND PROCESSING DELIVER ENHANCED ELASTICITY INTRODUCED TO CHINA
The announcement demonstrates the breadth and depth of the revolutionary Vistamaxx product platform, which is derived from the company's Exxpol® metallocene catalyst technology and proprietary process. The new products also expand the company's portfolio of nonwoven grades, including grades introduced late last year tailored for the specific needs of meltblown processing. "Typically, elasticity in nonwovens can be provided by combining existing materials in a composite structure or by mechanical means," said George Racine, product manager Vistamaxx specialty elastomers, ExxonMobil Chemical. "A breakthrough attribute of Vistamaxx is that the polymer itself has elastic properties, enabling the resulting nonwoven fabric to be elastic right out of the spunbond processing machine. Its elongation and tension set characteristics offer elasticity that's unlike other polyolefin polymers." The new Vistamaxx grades, VM-2125 and VM-2120, are being introduced at Chinaplas 2005 in Guangzhou, China. "Our exhibit at Chinaplas is key to us as this will be our first time in China promoting these two new products and having fabric samples for display. The China market is very important to us," stated Neo, Say-Lock, manager Ethylene Elastomers Asia Pacific. Vistamaxx VM-2125 (80 MFR, 0.865 density) exhibits high elasticity and low permanent set, while Vistamaxx VM-2120 (80 MFR, 0.868 density) offers medium-high elasticity and good recovery. Both grades offer excellent processibility. For nonwovens converters using spunbond technology, the latest Vistamaxx products offer an innovative way to provide cost-effective elasticity in nonwovens fabrics. They can be spun in most spunbond lines to produce fabrics at typical polypropylene conditions and rates. Web properties can be tailored by the selection of resin spinning condition and downstream treatment, resulting in fabrics over a wide range of elasticity that are soft, drapeable and tear-resistant. http://www.exxonmobilchemical.com
