Novel Melt Blending Technology Commercialized in Micro- and Nanolayer Films
The first two commercial devices have been installed to melt blend two or more polymers using a structured fluid-dynamic mixing process known as “chaotic advection.” This process creates unusual micro-scale and nano-scale phase morphologies that potentially can optimize extruded film properties using fewer materials and extruders than with highly layered coextrusion.

Shining Opportunities In Solar Films
Photovoltaic markets are growing explosively, and so are opportunities for specialty film producers. Solar cell and module production, which was forecasted to grow at 50% a year for the next few years before the recession hit, is now expecting slightly more healthy 30% annual growth, according to DuPont, a major supplier of photovoltaic film materials. Solar cell and module manufacturers are expanding, and large numbers of new companies are entering the field.
