Tetrapod shaped single crystal of zinc oxide(Pana-Tetra)

Pana-tetra is a needle-shaped crystal formed by zinc metal vapor and oxygen, and has grown in the C-axis direction of hexagonal crystal ZnO from each of the four alternate surfaces of a regular octagon. It is used for filters that provide outstanding filtering and duct collection characteristics due to the effects of its shape, excellent photo-catalyst activation with its semiconductor and ultraviolet absorption characteristics, and as antibacterial material made possible by its zinc ion effect.

Application example

1.Pana-tetra composite rubber

Pana-tetra composite rubber

2.Pana-tetra Composite Filtering Paper

[Filtering Characteristics]

  • The filtering efficiency of Pana-tetra filtering paper is higher than that of diatomite filtering paper. The same composition quantity generates approx. twice the filtering additive efficiency, enabling the use of thinner paper.
  • With an average dust grain size of 0.3µm, a filtering efficiency of 90% or higher was achieved.
  • The Pana-tetra filtering additive consists of zinc oxide in the shape of a tetra-pod with antibacterial and UV absorption characteristics



3.Supported Pana-tetra Non-woven Cloth Characteristics
  • Pana-tetra supported by a non-woven cloth achieved an improved dust collection performance.
  • Pana-tetra consists of a zinc oxide single crystal in a tetra-pod shape to which antibacterial, UV absorption, radio wave absorption characteristics, etc. can be added.
