How to Choose the Right Fireproof Fabric?

12 Mar.,2024

 

As the demand for flame retardant fabric has risen recently, many buyers who need help understanding this industry have gradually entered this field. Due to novices' ignorance of the industry, many cases of ineffective communication and being deceived have occurred.

Heaterk specially published an article to guide buyers to choose the products that suit them to save time and money and serve as a reference for future buyers.

1. The types of commonly used fireproof base fabrics, and the introduction of fire resistance

  


Ordinary Fiberglass Fabric

Alkali-free fire-resistant fabric: the most common glass fiber cloth on the market, white, with good insulation, long-term temperature resistance of 300°C and softening point of 500-750°C, above 300°C for long-term use is prone to embrittlement, not suitable for the acid environment

Medium-alkali fire retardant fabric: the insulation is poor, the strength is 10~20% lower than non-alkali, and the price is lower than non-alkali.

  

Expanded Fiberglass Fabric

It is obtained by weaving fiberglass yarn through puffing treatment.

The expanded fabric has better air permeability; filterability is thicker than ordinary fiberglass cloth and can cover thicker coating. A wide range is used in metallurgy, lime kiln, thermal power dust filtration, etc.


   


Steel Wire Reinforced Fiberglass Fabric

Steel wire is entrained in the fiberglass fabric weaving process.

It can solve the toughness problem of glass fiber used above 300°C, strengthen the whole, and prolong the service life of glass fiber cloth.

They are widely used in the exhaust, ventilation, waste gas treatment, etc.

  

  

High Silica Fabric

Silica fabrics are generally high-purity high-temperature resistant cloth woven from silica fibers with a silica content of 96%.

are generally high-purity high-temperature resistant cloth woven from silica fibers with a silica content of 96%.

High Silica Fiberglass Fabric is generally white and yellow. It can withstand the temperature of 1000 ℃ for a long time and 1200 ℃ for a short time, and the softening point is about 1700 ℃. It is also a kind of abrasion-resistant material.

The price is slightly higher and is often used in metal solution filtration, metals processing, power generation, and rocket-special high-temperature scenarios.

2. What is silicone fabric, and why is silicone fabric fireproof

     

 

Silicone-coated fabric is produced using glass fiber cloth as the base cloth, coated or calendered with silicone rubber and other materials. It is non-combustible, so silicone coated cloth fabrics can fire.

3. Why should the base fabric be coated, and what are the primary coatings?

  

The base fabric is not wear-resistant or resistant to folding, and it is easy to scatter when cutting and will cause itching to the human body. The coating can eliminate the above shortcomings and, at the same time, obtain the properties of the coating material, such as water resistance, oil resistance, and anti-corrosion so that it is suitable for more Application scenarios.

Aluminum Foil Fabric

As a commonly used cloth on the market, aluminum foil cloth has impermeability characteristics, high reflectivity, and a high shielding rate, but it is bonded with glue.

The aluminum foil is fragile, so it is easy to fall off in case of fire, and the aluminum film is easy to be burned through. It can only be flame retardant and is often used as an outer coating material. Not strictly fire-resistant coated cloth.

4. FAQ About Fireproof Fabrics

 

1. What is the difference between flame retardant and fire prevention

 

    Answer: The simple understanding is that flame retardant can isolate small fires, and cigarette butts will not burn when they fall on the ground. Fire prevention means separating space. The fire is burning below, and the fire cannot be seen above.

 

2. Is the silicone cloth fireproof? The thicker, the better.

 

    Answer: The thicker the substrate, the greater the mass per unit area, and the better the fire protection effect; the more comprehensive the coating, the better the flame retardancy, but the fire resistance may not be enhanced

 

3. How do you prove the fire resistance of your products

 

    Answer: The products we are producing can provide relevant test reports for buyers all year round
