Material Properties: It is melt-spun fiber with excellent acid and alkali resistance, good strength, elongation, wear resistance and chemical stability, as well as fine moisture-proof performance. Heat resistance: Slight shrinkage at 90℃. Elongation at break (%): 18-35. Breaking strength (g/d): 4.5-9. Softening point (℃): 140-160. Melting point (℃): 165-173. Density (g/cm³): 0.91.
Filter Cloth Classification: Polypropylene staple fiber filter cloth; Polypropylene filament filter cloth.
Filtration Performance: Polypropylene staple fiber is short and the spun yarn is fluffy; polypropylene filament is long with smooth yarn surface. Industrial fabrics woven by staple fiber are fuzzy on surface, delivering better effect in powder filtration and pressure filtration than filament ones. Fabrics made of filament feature smooth surface and superior air permeability.
Models: Polypropylene filament filter cloth: 521, 527, 534, 750AB, 8401(750A), 8402(750B);
Polypropylene staple fiber filter cloth: 2403(4212).
