Industrial filter cloth manufacturers of polyester cloth 260 240

Characteristics of polyester staple fiber cloth material properties: acid resistance weak base. Wear resistance, corrosion resistance, resilience good electrical conductivity is poor. Polyester fiber temperature is generally in the 130 --- 150 ℃, the product has an ordinary cloth mat class unique advantages, and wear very good, with a very high price to become the amount of maximum filter mat class varieties. Use pharmaceutical, sugar, food, chemical, metallurgy, industrial parameters heat resistance: 120 ℃, elongation at break (%): 20-50, breaking strength (g / d): 438, melting point (℃) 238 · 240 , melting point (℃): 255 a 260. Weight: 1.38. Filter performance: polyester staple fiber cloth material structure and short hair, woven fabric dense particle retention is good, but peeling, poor ventilation. Strength wear resistance, and no leakage of polyester filament cloth. Physical properties: Regain <0.4%, a specific gravity of 1.38. Mechanical properties: high strength 4 ~ 5.5g / D, better elasticity and elastic recovery, elongation of 15 to 30%, good wear resistance. Chemical properties: acid alkali. Heat resistance: dry temperature <200 ℃, wet temperature <220 ℃, a softening point of 230 ℃, a melting point of 256 ~ 265 ℃, heat distortion resistance and good stability.
