Polyester filter cloth refers to the filter material made of polyester fiber. Polyester filter cloth is divided into polyester long fiber filter cloth and polyester short fiber filter cloth. Polyester staple fiber filter cloth material properties: acid resistance, weak alkali resistance. Polyester filter cloth has good wear resistance, corrosion resistance and recoverability, but poor electrical conductivity. The temperature resistance of polyester fiber is generally 130-150℃. This product has the unique advantages of ordinary felt filter cloth, and has very good wear resistance and high cost performance, so it has become a large variety of felt filter materials.

Heat resistance: 120℃, elongation at break (%): 20-50, breaking strength (g/d): 438, melting point (℃): 238.240, melting point (℃): 255-260. Specific gravity: 1.38.

Filtration performance: The raw material structure of polyester staple fiber filter cloth is short and hairy, and the woven fabric is dense, with good particle retention, but poor peelability and air permeability. Strength, wear resistance and water leakage are not as good as polyester long fiber filter cloth.

Physical properties: moisture regain < 0.4%, specific gravity 1.38.

Mechanical properties: high strength 4 ~ 5.5g/d, good elasticity and elastic recovery, elongation 15 ~ 30%, good wear resistance.

Chemical properties: acid and alkali resistant.

Heat resistance: dry temperature < 200℃, wet temperature < 220℃, softening point 230℃, melting point 256 ~ 265℃, good heat resistance and deformation stability.
