Nomex fabrics for filters for gas emissions at high temperatures

Technofabric: Custom production of Nomex fabrics

Nomex fabric is a unique material that consists of aramid fibers, which are a type of synthetic polymer that DuPont invented in the 1960s. One of the main features of Nomex fabric is its ability to withstand high temperatures and flames, without melting, dripping or catching fire in the air. This makes Nomex fabric suitable for creating protective clothing for various sectors that face thermal hazards, such as firefighters, industrial workers, military aviators, motosport pilots, hospital gowns, and others. Nomex fabric also helps to reduce environmental pollution, as it can filter out harmful exhaust gases in different industrial plants that deal with hot processes, such as asphalt, cement, steel smelting, and nonferrous metal production. Nomex fabric has a flexible and elastic structure, which gives it a similar feel to natural fabrics. Nomex fabric is available in different forms, such as paper, felt, woven, and fiber.

The industrial processing of Nomex fabric involves several steps, depending on the form and the end use of the product. For example, to produce Nomex paper, the fibers are first dissolved in a solvent and then extruded into a thin film. The film is then dried and calendered to achieve the desired thickness and smoothness. The paper can then be cut into sheets or rolls for further applications1. To produce Nomex felt, the fibers are first carded and cross-lapped to form a web. The web is then needled to interlock the fibers and increase the density. The felt can then be treated with various finishes to enhance its properties2. To produce Nomex woven fabric, the fibers are first spun into yarns and then woven into different patterns and textures. The woven fabric can then be dyed, printed or embroidered with logos and symbols3. To produce Nomex fiber, the fibers are first cut into short lengths and then crimped to increase their bulkiness. The fiber can then be used for filling or blending with other fibers.

The main characteristics of Nomex fabrics for filters for gas emissions at high temperatures are:

Nomex filters are devices used to treat high-temperature gas emissions that come from various industrial processes. Nomex is a special fabric made of aramid fibers, which have the property of resisting heat and fire without melting, dripping, or burning in air. This makes Nomex filters capable of operating at temperatures up to 260°C continuously and 300°C in peaks, without degrading. Nomex filters also have good filtration efficiency, making them capable of capturing solid particles in exhaust gases, such as soot, ash, carbon, or heavy metals. In addition, Nomex filters have good resistance to chemical corrosion, which protects them from acids, bases, oxidizers, or solvents in exhaust gases.

Nomex filters are also lightweight, breathable, and flexible. They have low stiffness and high stretchability, allowing them to adapt to different shapes and sizes of filtration systems. They also have low shrinkability and good tensile strength and deformation resistance. Nomex filters are also durable and retain their protective properties even after numerous cleaning and regeneration cycles. The fire resistance provided by Nomex fabric cannot be washed out or worn away.

The technical specifications of Nomex are as follows:

Composition: 100% meta-aramid fiber
Weight: 100 to 800 g/m2
Thickness: 0.5 to 4 mm
Density: 0.2 to 0.8 g/cm3
Tensile strength: 200 to 1200 N/5 cm
Elongation at break: from 10% to 40%
Maximum operating temperature: 260°C continuous, 300°C peaks
Melting temperature: >370°C
ATPV: >8 cal/cm2
Electrical conductivity: <1 S/m

These Nomex filters are used in various industries that need to deal with gas emissions at high temperatures, such as asphalt, cement, steel smelting, non ferrous metal production, power generation, oil and gas refining, chemical and pharmaceutical production, waste incineration, and others. They are ideal for filtration systems that must ensure a reduction in pollutant emissions while complying with environmental regulations.

Nomex is a special fabric that resists heat and flames without melting, dripping or burning in the air. It is used to create protective clothing for various industries, such as racing, firefighters, military, industrial workers and others. Nomex is also used for industrial applications such as filters, conveyor belts, rubber membranes, thermal blankets, and loudspeakers. Nomex has characteristics similar to natural fabrics, such as low stiffness, high stretchability, low shrinkability, and the ability to be dyed. Nomex is produced and sold in different forms, such as paper, felt, fabric, and fiber.
