Dispersion Services
Five Star Technologies offers custom processing services for a wide range of material dispersions.
Using our patented hydrodynamic cavitation process, we are able to prepare custom dispersions from a
broad selection of particulates, fibers and flakes. Five Star has successfully processed a range of
materials including precious and base metals, metal oxides, boron nitride, barium titanate, various
glasses and carbon nanotubes. Dispersions may be processed in aqueous or organic solvent systems or
directly into liquid resin systems. Cavitation-processed dispersions are characterized by narrow targeted
particle size distributions, exceptional dispersion stability, and unique rheological control. Five Star
cavitation processing is a media-less, low-shear process, preserving product cleanliness and morphology.
Customer tests have demonstrated numerous advantages to the use of Five Star dispersions services.
- Dispersion uniformity that eliminates agglomerates and precisely controls maximum allowable particle sizes
- Rheological improvements in numerous applications
- Elimination of multiple processing steps
- No degradation of material purity; no contaminating media
- Maintenance of key material features such as morphology and coating integrity
- Ability to achieve high filler loadings
Dispersion services are available for lab through full production scale with batch sizes ranging from 1 to 100
gallons. All dispersion services are conducted at our cleanroom facility in Cleveland, OH, under strict quality
control conditions. Customers may provide a complete formulation for processing or contract Five Star to formulate
a stabilization system for a given filler/media combination.
