MOSCOW (MRC) -- Eastman Chemical Company, a global specialty chemical company, has introduced new product to the Cyphrex microfibers portfolio- a flat PET fibre, as per the company's press release.
New product possibilities are on the horizon for manufacturers of wetlaid nonwovens and specialty papers with the addition of a flat PET fiber to the Cyphrex microfibers portfolio. This fiber, with its novel cross section, enables functional benefits such as uniformity, lightweight strength and improved processability compared with other synthetic microfibers. Flat PET Cyphrex fibers are less than 0.4 denier in size.
"In just over a year since launching, we have begun to build a complementary set of Cyphrex™ microfibers for wetlaid nonwovens manufacturers," said Fred Dulin, director, microfibers platform, Eastman. "By offering round and flat fibers - in addition to the various sizes of Cyphrex - nonwovens producers can more precisely manufacture media to fit their customers’ needs, giving them an advantage in formulation capability."
Because flat PET Eastman Cyphrex™ microfibers disperse easily in water, they are compatible with standard wetlaid and papermaking processes and equipment. These fibers do not require special shear or agitation. In addition, they allow for easy incorporation with a broader range of fibers than most other synthetic microfibers. And the consistent cross section of the fibers can give wetlaid nonwovens manufacturers confidence in fine-tuning media formulations for desired functionality.
"As with the larger, 4.5-micron fiber added to the Eastman Cyphrex microfibers portfolio earlier this year, the flat PET fiber is part of our ongoing effort to create and give our customers innovative microfibers that fit their specific needs," Dulin said. "This is the latest example of how Cyphrex can keep creating new possibilities for wetlaid nonwovens manufacturers."
As MRC wrote previously, responding to a market need for a suitable material to use in hand-held and other electronic medical device housings that is tough and resistant to aggressive cleansers and disinfectants, Eastman Chemical Company is expanding its Eastman Tritan copolyester portfolio for the medical market with the introduction of Tritan copolyester MXF121. Tritan MXF121 is a bisphenol A (BPA)-free alternative to polycarbonate (PC) and PC/acrylonitrile butadiene styrene (ABS) that can stand up to today’s aggressive disinfectants and withstand the stresses of daily use and handling.
