PPS bags are high-performance dust collection bags made primarily from polyphenylene sulfide (PPS) fibers. Known for their excellent resistance to high temperatures, corrosion, high filtration accuracy, and good cleaning performance, they are widely used in various industrial fields. In high-temperature flue gas emission environments such as coal-fired power plants, waste incineration plants, steel mills, and cement plants, PPS bags can effectively capture dust particles, meet stringent environmental emission standards, and are particularly suitable for complex operating conditions containing acidic gases (such as SO2, SO3) and alkaline dust. In addition, PPS bags can also be used in flue gas purification systems in the chemical, metallurgical, and coking industries, ensuring equipment stability and extending service life, making them one of the important materials for achieving industrial dust emission standards.The exhaust gas from chemical reaction kettles containing chlorine and ammonia has a highly corrosive effect on filter material. After being dipped in PTFE emulsion, the PPS fabric forms a dense protective film on the fiber surface. After alternating aging for 48 hours, the strength retention rate remains above 85%. Its flame retardant index reaches UL94 V0 level, with an oxygen index of 34%, and it does not ignite even when exposed to high-concentration organic solvent flashes. The surface resistance of the coated film is reduced to 10?Ω, effectively preventing static accumulation and ensuring safe operation of flammable dust conditions. It can operate continuously for two years without replacement, providing enterprises with a safe, stable, and low-cost exhaust gas treatment solution.In industrial production processes, dust control is a critical step. PPS bags maintain stable performance under high temperature and humidity conditions due to their material characteristics, thereby extending their service life. Compared to other materials, PPS bags excel in acid and alkali resistance, making them suitable for handling flue gases containing corrosive gases. This makes them the preferred filter material for many industrial dust removal equipment.
