About PolyStar Technologies

PolyStar Technologies, Burnsville, MN, was founded in April 2003 by Mr. Kim A. Davis. The company engineers and manufactures premium, custom, sintered porous plastics. PolyStar's high-quality porous medias are used as fluid filters, vents, wicks, and diffusers in life science, medical, automotive, industrial, and consumer applications.

    A few of the specific applications include:
  • Vents and self-sealing valves for medical devices, caps and closures, and automotive batteries
  • Liquid filters for clarification of drugs, blood separation, and chemicals
  • Wicks and absorbent media for diagnostic testing
  • Fluid delivery components for printers, copiers, and fragrance wicks
  • Filters for air and water purification
  • Air, dust, liquid, and fuel filters for power tools and appliances

Our sintered porous plastic is naturally hydrophobic but can be made hydrophilic. The typical pore size range for sintered porous plastic is from about 10 microns to about 350 microns with typical void volumes ranging from 30% to 70%. We closely engineer and control pore size and void volume through the selection of specific polymers and process control.

    Our sintered porous plastic can be manufactured from a wide variety of polymers including:
  • Ultra High Molecular Weight Polyethylene (UHMW-PE)
  • High Density Polyethylene (HDPE)
  • Polytetrafluoroethylene (PTFE)
  • Polypropylene (PPR)
  • Polyvinylidene fluoride (PVDF)
  • Nylon 6
  • Polyethersulfone (PES)

The PolyStar Production Process

We have scientifically re-engineered the polymer formulation, tooling, production equipment, production processes, process controls, and quality assurance analytics to ensure robust, high-quality, continuously reproducible results. PolySmart ™, our unique and technologically advanced process innovations, encompass unique, broad-spectrum process improvements and the use of microprocessor-based adaptive process controls resulting in a consistently superior deliverable. These enhancements result in a consistency and reproducibility of process and product quality unmatched in the marketplace with manufacturing efficiencies that provide a significant contribution to meaningful competitive pricing and shorter lead times. Our speed and accuracy provides our customers with a significantly broader market opportunity for their products that incorporate a porous plastic component.
