Here, we will discuss porous polyimide films with a uniform pore structure, life science research tools with fine through holes, and other microfabrication products.

Porous Polyimide Film

Porous Polyimide Film With a Very Unique and Uniform Pore Structure

This is a porous polyimide film with an extremely unique and uniform pore structure.
This film has high heat resistance, high chemical resistance, and ultra-low dielectric constant, has excellent safety and insulating properties, and is intended for use as a substrate material and insulating film.

Features

  • Open cell structure with spherical pores
  • Consistent and uniform pore size
  • High porosity ⇒ high permeability, low dielectric constant
  • Low dielectric constant ⇒ Improved insulation and signal transmission

Life Science Research Tool With Microscopic Pores That Trap Cells and Allow Solutions to Pass Through.

These devices use transparent, anti-fluorescent materials with microscopic cell-sized structures. It is now being used by universities and research institutes around the world as a cell retention tool to supplement rare cancer cells in the fluid for genetic analysis, and as an analysis tool for the phenomenon known as NETosis/NETs (Neutrophil extracellular traps).
