Using the highest quality fiber materials and world-class needling techniques and equipment, HL Filter manufactures a wide range of Poylester PE needle punched felts with high dust-holding capacity and good air permeability. The Polyester media most commonly used and cost effective filter felt in modern pulse jet style baghouses. It is frequently used as a mixed felt of PE/PAN.
Bulk Roll Goods: weight, thickness, density, roll width, and roll length are customized at your request.
Most versatile, cost effective, and widely used
With good air permeability and also can be adjusted by customers' specific request
With high tensile strength and low tensile elongation
Provides an economical combination of good resistance to chemicals and excellent abrasion resistance.
Good for dry heat applications and superior to other synthetics with the exception of Nomex (Aramid) and PFTE (Teflon) in this matter.
Good choice for moist heat and subject to hydrolytic degradation under certain circumstances
Good resistance to most mineral and organic acids except high concentration of nitric, sulfuric, and carbolic acids
Good resistance to weak alkalis and moderate resistance to strong alkalis at low temperature.
Not recommend for high concentration of strong alkalis at high temperatures.
Continuous operating temperature 265℉ (130°C)
