C-Porous™ is a collective designation of our fluororesin porous products. This is the product that is made by giving a porous structure to PTFE with our original technology. As shown by the meaning of porous that it has “many” “pores”, it has both air permeability and water repellency while maintaining characteristics of fluoro resin.

Main applications:

[PTFE porous film]

filters / waterproof breathable membrane / electric wire coatings / cable protection / heat insulation.

Overview

This porous film constitutes of 100% PTFE. While it keeps air permeability due to the pores, it maintains waterproof and water repellent performance. Combined products with nonwoven or glass cloth and punching processed products are also available.

Main application

  • Wire coating
  • Filter
  • Heat retaining material
  • Filters
  • Air vents
  • Degassing
  • Bubbling

Characteristics

  • It has waterproof and water repellent performance while maintaining air permeability.
  • It is also excellent in heat insulating characteristics, flexibility, lowest friction, weather resistance and chemical resistance.
  • Punching with various shapes is possible.
  • We can also manufacture strong non-woven cloth type, glass cloth type and oil-repellent type. Please consult us separately.
  • Excellent air permeability.
  • Micropores provide both waterproof and water repellent performance while maintaining air permeability and moisture permeability.
  • Oil-repellent type is also available.
  • We can also offer products with seal treatment, in a punched format, a sheet format or other appropriate formats.

PTFE porous tubes:

This is a soft and thick sheet composed of 100% PTFE porous film. It has the chemical resistance and is hard to deteriorate even when impurities are eluted or after long term use. These rods has high water repellency and air permeability, and it can be changed by adjusting the porosity. We can also manufacture rod shaped products and multi lumen products.

  • It has waterproof and water repellent performance while maintaining air permeability.
  • It is also excellent in heat insulating characteristics, flexibility, lowest friction, weather resistance and chemical resistance.
  • We can also manufacture multilumen products.
  • It has excellent heat insulating characteristics.
