Fluororesin (PTFE) porous tube / TEF-100 series
Fluororesin porous tube with high water repellency and air permeability.
This is a product made by porousizing PTFE. It has high water repellency and air permeability, and the air permeability can be adjusted by changing the porosity. It excels in dimensional stability and flexibility, making it difficult for dimensional changes to occur even when constructed into complex shapes in high-temperature environments. Additionally, as it is made of pure PTFE, it does not deteriorate due to various chemical solutions. It is also possible to manufacture rod-shaped or multi-lumen types.
