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

Unique and Uniform Microstructure

Intended Use Case

• Various Separation Membranes
  (Lib Separator, etc.)
• Low-Dielectric
  Substrate Material
• Sound-Proof/Sound-Absorbing Materials
• Heat Resistant/Insulating Materials

Microphysiological system（MPS）

Fluid3D-X: the cutting-edge MPS chip for drug discovery, and the perfusion culture system,both developed through our core microprocessing technologies.

Featuring a double-layer microfluidic channel structure equipped with a microporous membrane, the microfluidic chip is designed for optimal pharmacokinetic evaluation.

Features

• Plastic is used as a chip material to achieve low absorption.
• A unique manufacturing process enables flexible microchannel design change.
• Low cytotoxicity and good observability (fluorescence/phase-contrast)
