Polypropylene liquid filter bag


Polypropylene liquid filter bag


Polypropylene (PP) polypropylene has good wearability and high resilience. It is an excellent thermoplastic fiber. Polypropylene felt is often used in low-temperature pulsed filter bag and chemical and pharmaceutical plant pulse bag. Under the operating temperature of 130 C, the heat resistance is less than polyester. But polypropylene fiber has good chemical stability. Besides being corroded by concentrated sulfuric acid and concentrated nitric acid, it is stable for all kinds of chemical reagents and has good anticorrosive effect. But the low molecular weight of fatty hydrocarbons and aromatic hydrocarbons can soften and expand the PP. The filtering precision is in the range of 1-200um.
