The technical glass fiber fabrics

Introduction

When it comes to the production of technical fabrics, the possibilities are almost endless. Whether woven rovings made of glass or carbon, technical fabrics as coating carrier or for filtration, the production options are vast:

-Traditional mesh structures with leno weave technique
-Compact and closely woven fabrics with air-jet or rapier weaving machines
-Warp beam weaving and creel feeding possible

Glass fiber product solutions for the coating industry:

The coating industry is very diversified, which leads to a wide range of requirements for the products used in this sector. our technical textiles, produced from glass fiber , offer a wide range of applications in this area thanks to their individual raw material and coating variants. Such as fire blankets for metal welding and cutting or grinding,for EV car fire or home application;fire curtain or smoke curtains;fire bag for battery proection;induction blankets;heat shields;etc.

Custom technical parameters

Fabrics made from glass fiber are used in a variety of ways in the coating industry.

The specific material properties of the coating carriers mean that the technical parameters of the coated fabrics, such as maximum tensile strength or elongation and shrinkage behavior, can be tailored perfectly to the intended application.

Custom raw material combinations and coating options

The coating industry field is very diversified, which leads to a wide range of requirements for the products used in this sector.

The manufacture of technical fabrics can be tailored just as individually. The yarns and rovings used are made of glass, aramid or Gualon, for example. If desired, another additional coating can be subsequently applied, for which silicone, acrylate, PTFE/Teflon, graphite, fluorocarbon, polyurethane as well as various fire- and flame-retardant materials are available.

Different coating material finished fiberglass Fabrics

These fiberglass fabrics are widely used for thermal insulation, acoustic insulation, and for protection from heat and fire. These woven high temperature fabrics support operating temperatures up to 1000°F / 540°C and peak temperatures up to 1300°F / 700°C. This flame retardant fabric is made from inorganic materials so they will not produce hazardous out-gassing.

Applications

This fiberglass cloth is available with a variety of high temperature coatings and treatments for specialized high-temperature applications.

Specifications

Vermiculite Coating

The proprietary vermiculite coating increases the operating temperature resistance of the fiberglass fabric to 1500°F (815°C) and peak temperature resistance to 2000°F (1095°C). This high-temperature coating also improves abrasion resistance.
The vermiculite coated fiberglass fabrics are commonly used in fire curtains, fabric expansion joints, and pipe or tank insulation systems.
HardTape Vermiculite Coating for Improved Temperature and Abrasion Resistance
Our Vermiculite Coating is one of our most reliant high temperature coatings; it causes heat to disperse evenly across the surface of the fiberglass fabric, significantly boosting its temperature rating and abrasion resistance. Vermiculite Coated Fiberglass Fabrics withstand operating temperatures up to 1500°F / 815°C and peak temperatures up to 2000°F / 1095°C.
The Vermiculite Coating has larger platelets and a greater percentage of solids than competitive vermiculite coatings. The larger platelets give the high temperature coating better coverage and allow it to more effectively disperse heat across the surface of the fabric. In addition, the Vermiculite Coating features an organic adhesion promoter that reduces flaking and wear while improving moisture resistance.
Materials used to fabricate high temperature gloves, welding blankets, or insulation blankets are often treated with a vermiculite coating.
-Wire inter-woven Fabric: this Steel wire reinforcement fabric increases the strength and durability of these fiberglass fabrics for improved performance in high vibration or abrasive high temperature environments.
These strong flame retardant fabrics are commonly used in fire retardant curtains, equipment and pipe insulation, and other high temp insulation systems.

Rewettable Coating treated fabric

A Water-Activated Coating that Dries Hard to Form a Barrier

The rewettable coating is an inorganic clay-based coating applied to HardTape Fiberglass Fabrics for encapsulation applications. This high temperature fabric can be moistened at the application site and then dries to create a hardened paint-able surface, making it ideal for use in high temperature insulation, lagging, and encapsulation applications, like asbestos abatement. these fabrics are coated with a water-activated clay that dries hard to create a firm, fire resistant material.

The rewettable coating can withstand temperatures up to 1000ºF / 540ºC.

Common Applications include :Encapsulation,Asbestos Abatement,Insulation Systems,Lagging

Additional colour treated or coated glass fiber fabrics

For Ease of Identification and Improved Handleability

We offer black, yellow, red, blue, green, orange, and salmon color treatments. Color-treated fiberglass fabrics and coated fabrics are used in a variety of industries for aesthetic or identification purposes. Color treatment does not significantly change the heat rating of a fabric, but it does provide added benefits including improved handling, increased weave stability, and fewer broken filaments.

We can create custom dye colors upon request for large orders. Contact us for more information.

above mentioned fiberglass cloth can be color dyed for aesthetic or identification purposes. They can also be treated with lightweight coatings designed to reduce fray and irritation or improve resistance to oil and water.

Silicone and PTFE glass fiber fabrics resist weather, water, chemicals, and oil

Silicone and PTFE Coatings for Abrasion, Weather, and Chemical Resistance

Our PTFE and silicone products are commonly used as the outer layer in fabricated systems that protect insulated pipes and equipment from the environment. These fabrics are also frequently used in products that protect workers and facilities from heat and fire. They offer superior resistance to chemicals, abrasion, moisture, and heat. The PTFE coating provides added toughness and chemical resistance while the silicone coating provides strong weather, water, and abrasion resistance. The silicone coating comes standard in silver, but it is also available in red by special request for large orders.

The silicone coating can withstand peak temperatures up to 500°F / 260°C and the PTFE coating can withstand peak temperatures up to 600°F / 315°C. The coatings will char or disintegrate at these temperatures, however, the base fabric beneath the coating likely has a higher heat tolerance.

Aluminium foil laminated glass fiber fabrics

While HardTape’s advanced aluminized fabrics are primarily used to create garments for firefighters and industrial workers,the potential uses of HardTape aluminized fabrics are limitless due to the unique insulation and heat reflective properties of the material. The aluminized surface is also impervious to most aqueous and hydrocarbon-based compounds, as well as being high temperature resistant and flame retardant.

If your application requires one of these properties, we probably have the right material for you.

Enhances Ease of Handling and Fabrication

Glass fiber fabrics Heat Cleaned (HC)

Heat Cleaned fabrics are treated at high temperatures to remove broken filaments and manufacturing finishes like binders and lubricants. The process improves weave stability while reducing skin irritation and airborne fibers. Removing manufacturing finishes also reduces the amount of smoke the product will generate when exposed to extreme temperatures.

Fabrication Treatment (FAB)

Fabrication Treatment is an acrylic coating applied to one side of the fabric. The treatment is designed to improve weave stability and abrasion resistance, prevent fraying and make the fabric easier to cut.

Regular Treatment (RT)

Regular Treatment is a very light acrylic coating applied to improve weave set and reduce skin irritation. The Regular Treatment is a lighter coating than the Fabrication Treatment. It is applied to both sides of the fabric and resists temperatures up to 1000°F / 540°C. Regular Treatment does not impact the strength of a fabric.

Oil and Water Resistance (OWR)

Oil & Water Resistance is a lightweight protective coating applied to fabrics to prevent wicking and to improve resistance to oil and water. It improves abrasion resistance and tolerates temperatures up to 1000°F / 540°C.

Filtration fabrics of glass fiber

Glass fiber woven fabrics are widely used in different filtration application area

From reinforcements for filter media to custom technical textiles for solid/liquid separation, hot gas or particle filtration.

Since filter media are subjected to considerable daily wear, it is important to reinforce them sufficiently. we produces special support and protective fabrics that have the necessary strength and stability. Customized technical textiles for solid/liquid separation, hot gas or particle filtration can also be designed according to customer requirements.

Our glass fiber woven fabrics for filtration application have following advantages:

-Strength and stability

For applications in wet filtration, where solid-liquid separation takes place, the filter medium used must be able to withstand the strong, continuous, and constantly fluctuating pressure forces which are sometimes at work.
By introducing a support and protective fabric in the form of a woven mesh fabric, the filter is given the necessary stability and strength to ensure a long service life.
In particle filtration (air purification), the glass or cotton mats used can also be additionally reinforced and protected by means of a woven mesh fabric. They have the advantage of being easy to handle so as to make assembly at the customer’s end as efficient as possible.

-Excellent thermal and chemical resistance

During hot gas filtration in incinerators, the filter media is sometimes exposed to high temperatures or chemical vapors.
our filtration fabrics can be produced from various raw materials such as glass, polyester HT, aramid and other synthetic fiber materials and thus tailored to specific requirements.
Filtration fabrics made of glass fiber materials for solid/liquid separation, hot gas or particle filtration.
The materials are selected for the different fabric constructions in line with the desired filtration effect and resistance.
