Aramid/Nomex/Kavlar Air Slide Fabrics

General introduction of aramid air slide fabric:
Aramid air slide fabric also called Nomex air slide fabric and Kevlar air slide fabric in the market due to the raw material from the different suppliers. According to the different working circumstance, the aramid materials from Zonel Filtech were adopted the aramid 1313 (similar to Nomex) and aramid 1414 (similar to Kevlar) according to the certain working circumstances.

Aramide air slide fabric, nomex air slide membrane, kavlar air slide membrane

The Aramid 1414 air slide fabric which is fire proof, high tensile strength and abrasion resistance, longer service life, the maximum operation temperature resistance even up to 250degree C.

Aramide air slide fabric, nomex air slide membrane, kavlar air slide membrane

For the aramid 1313 air slide fabric, which is the high temperature resistance air slide fabric as well, this aramid air slide belt continuous operation temperature can up to 200degree C, maximum peaks can up to 220degree C. This aramid air slide belt with shorter operation life and lower operation temperature, but can offer a more economical solutions for some special air slide systems.

Aramide air slide fabric, nomex air slide membrane, kavlar air slide membrane

Aramid fiber also can be needle punched into nonwoven aramid air slide fabric (Nomex nonwoven air slide fabric) and offer some economical solutions for the air slide systems or homogenization systems.

Relevant specification of the aramid air slide cloth from Zonel Filtech:
Thickness of the aramid air slide membrane: 3~10 mm can be customized.
Width of the aramid (Nomex) air slide belt: max. 2.4 meters.
Air permeability: can be customized as requirements.
Tensile strength: > 5000N/4cm.
Temperature resistance: -60~250 degree C.

Properties:
1. Clear veins, stable size, high tensile strength, various materials for choosing according to the different requirements.
2. Equal air permeability, the tolerance of air resistance is within ±10%.
3. High temperature resistance, abrasion resistance, little hygroscopicity, corrosion resistance, lower adhesive capacity, never delamination, longer service life.
4. Smooth surface, 100% new materials, won't leak dust, green products.
5. The products applicable to convey the materials with the particle diameter < 4mm, temperature < 250degree C, the moisture content < 2%.

Applications:
For some high temperature particles/dry powder air slide conveying.

Zonel Filtech provide good quality polyester spunbonded nonwoven fabrics for industrial filtration application. (filter cartridge media)

The polyester spun bonded filter cloth with the special designed pattern, combined with the 3D spunbonded lapping workmanship, make the spun bonded filter cloth from Zonel Filtech with the properties of good air permeability; high filter efficiency; high stiffness and not easy to change the shape once pleated; big particles load and durable for various industrial applications. The spun bonded polyester nonwovens from Zonel Filtech can be finished with PTFE membrane laminated, water & oil repellent, and laminated with aluminum foil for anti-static and so on to meet the different requirements from different operate conditions.

Besides the spunbonded filter cloth, Zonel Filtech also provide the sound quality membrane support layer for pleated type filter cartridges.

Polyester air slide fabric

General introduction of Polyester air slide fabric:
Zonel Filtech provide good quality polyester air slide fabrics for air slide systems, which can be divided into polyester spun yarn air slide fabric, polyester filament air slide belt and polyester nonwoven air slide cloth for different usages and requirements from the clients.

Polyester air slide fabrics/polyester air slide membrane/polyester air slide belt

The filament polyester air slide fabric with a smooth surface and equal air permeability, strong construction, excellent for abrasion resistance, with the longest service life for the polyester material air slide fabrics.

Polyester air slide fabrics/polyester air slide membrane/polyester air slide belt

The spun yarn polyester air slide belt with the same construction as the filament air side membrane, also offered to various industries for dry particles conveying and mixing the material in homogenization silo, etc, but the service life shorter a little when compare to the filament one, but price cheaper some.

Polyester air slide fabrics/polyester air slide membrane/polyester air slide belt

Nonwoven air slide belt, with the needle punched nonwoven construction (nonwoven polyester air slide cloth), air permeability bigger, and softer, easy installing, and suitable for some small volume and light material conveying, which is the most economical solutions of the air slide fabric for the air slide systems.

Relevant specification of the polyester air slide fabric from Zonel Filtech:
Thickness of the polyester air slide fabric: 3~10 mm can be customized.
Width of the polyester air slide belt: max. 2.4 meters.
Air permeability: can be customized as requirements.
Tensile strength: > 5000N/4cm.
Operation temprature: -60 dgree C to 150 degree C, max. peaks: 180 degree C.

The properties of the air slide membrane from Zonel Filtech:
1. Clear veins, stable size, high tensile strength, various materials for choosing according to the different requirements.
2. Equal air permeability, the tolerance of air resistance is within ±10%.
3. High temperature resistance, abrasion resistance, little hygroscopicity, corrosion resistance, lower adhesive capacity, never delamination, longer service life.
4. Smooth surface, 100% new materials, won't leak dust, green products.
5. The products applicable to convey the materials with the particle diameter < 4mm, temperature < 180degree C, the moisture content < 2%.
