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

・The Porum PH series is made using Tokuyama's proprietary biaxially-stretched tubular process to ensure a soft texture and good stretchability, as well as strong and balanced crisscross stitching that makes the material hard to tear. When Polyethylene sheets filled with calcium carbonate as refined inorganic filler are stretched bi-axially, the overlapping surfaces of the filler and polyethylene are detached and voids are created there, forming an integrated microporous structure.

・The Porum PM series provides excellent cost performance and processability at customers' production lines.
