What Is POREFLON? | Sumitomo Electric

Features of POREFLON

Chemical resistance

Can be cleaned with chemicals from pH 0 to 14, including high-concentration alkalis

Thermal resistance

Resistance to high temperatures allows use in membrane filtration applications up to 200°C

Durability

Durability against shaking and flexing allows use for extended periods

Permeability

High porosity ensures high permeability and excellent water treatment capability

Porous material made of 100% PTFE

The white fibers in the SEM image are PTFE fibers, and the dark areas are the spaces (pores) that allow water to pass. POREFLON can be manufactured with a pore rate (porosity) of up to around 90%. (This excludes strength and other restrictions.)

Porous material made of 100% PTFE Production pore size range: 0.03 to 10μm
