Product Name: High Tensile Strength Polyester Filter Media Model NO.: 07-26 Paper Type: Qualitative Manufacturing Method: Manufacturing Cloth Hole Shape: Round Type: Filter Felt Usage: Air Filter Material: Polyester Trademark: tianyu Transport Package: Plastic Specification: 1.8-2.2m Origin: China Product Description High Tensile Strength Polyester Filter MediaDescriptionPolyester, being a "commodity" fiber, is available in a significant range of deniers (effectively diameters) and so a wide range offilter mediaproducts can be designed to match the demands of the filter; from very high collection efficiency (with very fine fibers) to low efficiency products (using coarse fibers) where flow is more important than collection.A wide variety of chemical and thermal treatments are available for polyester, the most common being superglaze to improve dust release and liquid repellency to assist with sticky dusts.SpecificationMaterial100% PolyesterWeight500±25g/m2Air Perm8-12 m³/*minWarp Tensile Strength>900N/5×20cmWeft Tensile Strength>1200N/5×20cmWarp Elongation<25%Weft Elongation<45%ContinuousTemperature130ºCSurge Temperature150ºCMoist Temperature94ºCFinishingSinged, smooth, stabilizationChemical Resistance:Acid FairAlkalis FairOxidizationAgents GoodAvoid strong alkali and acid environments at elevated temperatures - the most versatile of the low temperature fibers, used in the cement and quarry, metal processing, flour and wood industries.Finishing :heat setWhen fibers are manufactured they invariably have a residual tendency to shrink in length when heated substantially. After these raw materials are converted to filter felts, they need to be heat stabilized to ensure that any shrinkage in the final application is minimized.There are a number of ways of achieving this, but in essence, all require that the filter mediais exposed to a temperature comfortably above the expected operating temperature. The material has then has to be held at that temperature to ensure that the in-built stresses are relaxed out.The result is a stabilizedfilter mediawhich will exhibit minimal shrinkage at the anticipated operating temperature.
