Polyester needle felt, 500g/m2

Our company produces 3 types of needled felt, i.e. pure glass fiber needle felt, compound fiber needle felt and synthetic fiber needle felt.The compound needled felt is made with a certain amount of synthetic fiber blended into the felt. Synthetic fiber has stronger interlocking capability. Compared with pure glass fiber needle felt, the peeling strength between felt and base fabric and friction resistance has increase 3 or 4 folds. Thus its service life is strikingly prolonged.The synthetic fiber needled felt is made from P84, PPS, PTFE, Kermel and Metamax.It has three-dimensional micro porous with high porosity and low resistance. The dust separation efficiency is up to 99.9%, higher than that of woven fabric. This product is suitable to bag filters with impulse jet or high velocity reverse air clean-down technology.The compound needled felt is mainly used for cement and carbon black industries, and the synthetic fiber needled felt is mainly used for dust separation of coal-fired boiler and precious metal recovery in non-ferrous metallurgy.MaterialsPPSP84MetamaxKermelPPAcrylicPTFEPolyesterMass (g/m2)500500500500500550750750750500Tensile Breaking Strength (N/50mm)Warp≥1000≥1000≥1000≥1000≥1500≥800≥700≥700≥700≥800Weft≥1200≥1200≥1200≥1200≥1800≥1100≥800≥800≥800≥1200Tensile Breaking Elongation (%)Warp≤30≤30≤30≤30≤28≤25≤16≤18≤18≤35Weft≤50≤50≤50≤50≤35≤45≤18≤20≤20≤50Air Permeability (cm/s) @127Pa15 3015 3015 3015 3015 3015 3012 302 612 3015 30TreatmentSinged, Calendar, Heat Setting, Acid ResistantHeat SettingPTFE MembraneDippingOil & Waterproof, Acid Resistant, Antistatic,Singed, Calendar, Heat SettingTemperature (oC)≤190≤260≤200≤22090140-190 260130-150Recommended Air Flow (m/min)<1.5
