The PP needle punched felt is widely used in liquid-solid filtration. Besides some properties as ordinary filter felt have, the properties of anti-acid, anti-alkali and lower soften point of PP are better than polyester, and its stability of water solution is excellent, so PP needle punched filter felt is often used in the field with fume temperature under 100ºC, the density of acid and alkali is high or the field of filtering solid from liquid that the density of acid and alkali is high.

PP needle felt can be produced by ordinary staple scrim or high strength filament scrim, due to the customer demands with different thickness, wideth, and lengths:

• Weight ranges from 200 g/m2 to 2000 g/ m2
• Thickness ranges from 1.5mm to 6mm
• Possible length from 160mm to 220mm, max up to 350mm
• Different treatment are possible

Features and Benefits:

• Smooth surface, more defined pore size and good air permiability
• Low temperature resisitance ( 88-110 ºC)
• Excellent resisitant to hydrolysis, acids and alkalis
• Low fiber release, Low density
• Reasonable price
• High mechanical characteristics
