polyester needle felt

Polyester Needle Punched Felt Weight: 500g/m2 Material: PET fiber/ PET long thread scrim Thickness (mm):2.0mm Air Permeability (m3/m2.min):15~18 Warp tensile strength: >1000N/5x20cm Weft tensile strength :> 1300N/5x20cm Warp elongation :< 25% Weft elongation: <55% Finishing: Singed, Canlendered, heat setting Operating Temperature (°C): Continues: 135 Instant: 150 The weight (300~650 grams) and width (within 2.3 meters) can be customized! We can finish them with singeing, calendering, heat setting, Teflon coating and membrane. polyester needle felt adopt nonwoven workmanship, wide use for industrial dust collector,prevent air pollution project . After heat setting treatment and calendering treatment, the surface is smooth,with the property of stable physical dimension,easy cake release, good air permeability. After wate-oil repelled treatment,can be use in the circumstance of moisture and oil mist for a long time. We also can make a finish treatment with PTFE membrane on the surface of polyester needle felt, which with the property of smooth surface, water repelled,easy cake release,high filter efficiency,save energy,long life.
