This woven fiber is widely chosen for its lightness, high strength and excellent resistance to most acids and alkalis. The sleekness of the fiber allows for excellent cake release. Since its moisture absorption is virtually nil, polypropylene is a good choice for an application such as dye production, where pigment changes can be made with only a light wash between batches. A latex border can be applied to the individual cloths to provide greater gasketing and sealing properties during the operation.

HEAT RESISTANCE: 190 ºF

Non-woven and calendered, polypropylene felt has all the attributes of polypropylene, including lightness, high strength and excellent resistance to most acids and alkalis, with the added benefit of improved cake release due to the calendered surface and greater gasketing or sealing properties due to the increase in the thickness of the cloth. To further improve its sealing qualities, a latex border can be applied to the individual cloths.

Polyester filter and dust collection fabrics have very good resistance to chemicals, abrasion and dry heat degradation, plus excellent dimensional stability. Typical applications include dust collection, particularly in the cement industry; acid refining of ore; anode bags for electroplating; tubular battery separation fabrics.

HEAT RESISTANCE: 275 - 300 ºF

Polyester fibers are compressed and finishes are applied according to the process or application they are used for. All of the excellent characteristics of polyester apply to polyester felt, including good resistance to chemicals, abrasion and dry heat degradation, plus excellent dimensional stability. Polyester felt is most commonly used in dust collection processes, where the air flow is either forward or reverse pulse. The direction of the air flow dictates the finish required.

Polyester Felt is available in rolls… minimum order: 100 yards

HEAT RESISTANCE: 275 - 300 ºF

Because of its high abrasion resistance, nylon is used in filtration of abrasive dusts or wet abrasive solids at low temperatures. Nylon's good elasticity makes it ideal for conditions where continuous flexing takes place. This fabric is a good choice in wet filtration applications, at low temperatures and in an alkaline atmosphere, for example in dyestuffs. Fabrics of nylon provide excellent cake release.

HEAT RESISTANCE: At up to 260 ºF, nylon has reasonably good dry heat resistance. It is superior to acetate, modacrylic and saran, but most other synthetics are superior to it. Nylon performs adequately in moist heat temperatures ranging up to 225 ºF however its high initial tensile strength and abrasion resistance will make it a preferred choice in a number of applications.

The use of cotton material for industrial filtration applications has declined over the years as the use of synthetics such as polypropylene and polyester has taken over most processes. Cotton used in a filter press operation will swell, creating a better seal and gasket effect during the process.

HEAT RESISTANCE: 225 ºF

All cotton styles available pre-shrunk or greige (unfinished).

Conductive (Anti-Static) cloth is a synthetic material, most often a polyester, woven throughout with stainless steel wire or carbonized filament to dissipate static electricity. Non-conductive material is also usually polyester, but does not contain these metal wires or filaments and is therefore, ineffective in the dissipation of static electricity. Conductive (Anti-Static) is more commonly used in industrial applications. The addition of the wires and filaments has no affect on micron or porosity readings of the cloth. It is simply added to dissipate static electricity during the use of the material. Conductive (Anti-Static) cloth is most commonly used in the manufacture of replacement bags, socks, chutes and sleeves for fluid bed dryer equipment, high shear granulators, mixers, blenders, milling operations, hoppers and discharge chutes.

Non-Conductive Styles - The following specifications include only Conductive (Anti-Static) styles. Non-Conductive styles do not contain carbon or steel and are less commonly used. For specifications and further information about the Non-Conductive styles available please contact us.
