Polypropylene fiber owns common these characteristics as follows: acid-proof and alkaline resistant; good abrasion resistance and bad corrosion resistance; good reversibility and strong conductivity. Its elongation is 18-35%. But, its heat-resistant function is very bad, so when the temperature is up to 90°C, it happens to shrink. Most of Polypropylene filter fabric? performance resembles polyester filter fabric?. It is used widely in pharmacy, china, chemical engineering, metallurgy and manufacturing, as the filter bottom in the mineral processing etc. The regular types of Polypropylene filament filter fabric: 52l\527\534\750\522\108\850...etc. The regular types of Polypropylene staple fiber filter fabric: 4212
