C-Porous™ PTFE porous products

C-Porous™ is the general name for Chukoh Chemical Industries, Ltd. 's fluoroplastic porous products.
This is a product in which PTFE has been made porous using our own technology. Porous means that there are "many" "pores". By applying our own method to make fluoroplastic (PTFE) porous, we have achieved air permeability and water repellent performance while retaining the properties of fluoroplastic (heat resistance, chemical resistance, Weatherability, electrical properties, etc.).

Main Applications

[PTFE porous film]
Filters / waterproof and breathable membranes / wire coatings / cable protection / heat insulation materials

[PTFE porous tube]
Filter/Oxygen sensor/Bubbling/Degassing/Suction/Exhaust

[PTFE thick-walled porous tube]
Chemical protection/Heat insulation material/Pipe protection

PTFE Porous Film

This is a film-like product made by making PTFE porous. It can be punched into various shapes. Oil-repellent and non-woven types are also available.

ROHS Directive

PTFE Porous Film SEF-600

This product is made by making PTFE porous and forming it into a film. Compared to the porous film SEF-010 series, it has superior air permeability and water resistance. It is available in a wide range of widths while maintaining the stiffness required for easy handling.

ROHS Directive

PTFE porous film composite

This product is a composite of a porous PTFE film and nonwoven fabric, mesh, etc. Compared to the porous film SEF-010 series, it has high breathability and water resistance.

ROHS Directive

PTFE Porous Sheet SEF-200

This is a soft, porous sheet made of 100% PTFE, which does not use any adhesives made from fluoroplastic (ePTFE). In addition to the properties of fluoroplastic, it has heat insulating characteristics and flexibility.

PTFE Porous Tube TEF-100

This is a soft tube that has fine pores that provide air permeability and moisture permeability while also providing waterproof and water-repellent properties.

ROHS Directive

PTFE thick porous tube TEF-110

A thick porous tube with excellent heat retention (heat insulating characteristics), flexibility, and chemical resistance.

ROHS Directive

PTFE Unsintered Porous Tape SEF-110

This product has a low dielectric constant and small dielectric loss. It is suitable for insulation coating applications. It is available in two colors: white and black.

ROHS Directive

ASF-130T

This adhesive tape has a porous film made of fluoroplastic (ePTFE) as the base material. In addition to the properties of fluoroplastic, it also has heat insulation, waterproofing, and water repellent performance.
