Eastman Chemical is introducing a 4.5-micron diameter PET microfibre specifically designed for wetlaid processing in response to a demand from the market for expanded formulation options with fine fibres.
This addition to the family of Cyphrex microfibres comes less than a year after the successful launch in April 2013 of Eastman's commercially available 2.5-micron diameter microfibre.
When blended, these highly uniform microfibres can allow the formulator to help pinpoint permeability and control pore size, resulting in greater precision for targeted functionality.
