Our factory selects 100D/160 and 500D/120 mixed Mioro-polypropylene fiber from Dupont Teijin fiber Co., Ltd, then composited with basalt fiber adopting advanced international standard and the equipments to produce micro PP needle punched filter felt. The past finished treatment includes singeing, calendaring, adding the basalt coating treatment.

Features:

• Smooth surface, more defined pore size and good air permeability 

• Low temperature resistance ( 88-110 ℃) 

• Excellent resistant to hydrolysis, acids and alkalies. 

• Lower fiber release, Lower density,High mechanical characteristics

Applications:

• Galvanic industry and Chemical industry 

• Prefiltering solvents and acids 

• Prefilter to extend final filter life 

• Final filter for noncritical filtrations 

• TLiquid-solid sepration with strong acid and alkali conditions filter press 

• Air filtration under 100℃
