Where does extensional mixing perform best?
Extensional Mixing is ideal for: a. Handling particle dispersion and particle size reduction where requirements are to break up agglomerates. It lends itself to single- screw compounding, in many cases allowing direct compounding without the need for masterbatching. b. Creating excellent dispersion on nanoclays, with full exfoliation, and allowing improved dispersion of carbon nanotubes, from making masterbatches to direct compounding. c. In many cases where color pigments are hard to disperse, needing multiple passes to reduce pigment size, extensional mixing can accomplish that in one pass. Tests have shown that 70 µm random particles exiting a twin-screw extruder can be reduced to 10 µm size after passing through a Tek-Mix™mixer. d. Reduction of gels (ie: scissioning of high molecular weight long-chain particles that plug screens and create stress-multipliers in films and parts), tests have shown up to 75% reduction of long-chained molecules that create gels, without affecting the o
