Product overview

The NF Sheet is a polypropylene microporous film that repels water but allows air and moisture to pass through. Tokuyama also offers the NFR Sheet, which can be combined with non-woven fabrics and cloth yarn.

Special characteristics

・Excellent air and moisture permeability allows air, moisture, and gas to pass through

・Water resistant enough to effectively prevent water from passing through

・Irritating or harmful gases are not emitted even when burned

・Excellent air permeability is achieved via Tokuyama's proprietary biaxially-stretched tubular process

・Compared to conventional microporous film made from polyethylene, the NF Sheet has elasticity and demonstrate superior air permeability and heat resistance.

・The NFR Sheet exhibits extremely good heat sealing properties in addition to the special characteristics of the NF Sheet described above.

As shown in the photo, when polypropylene sheets filled with calcium carbonate as refined inorganic filler are stretched bi-axially, the overlapping surfaces of the filler and polypropylene are detached and voids widened longitudinally and laterally are created there, forming an integrated microporous structure.
