Blended Glass Fiber Filter Bag High Temperature Resistant Anti-corrosion Industrial Cement Kiln Dust Collector Bag
Our blended glass fiber filter bags adopt high-purity glass fiber blended with multi-component high-temperature resistant fibers, breaking the limitations of single glass fiber and ordinary high-temperature filter materials. It supports long-term stable operation at 260℃ and withstands instantaneous high temperature of 280℃, with ultra-low thermal shrinkage and no thermal deformation. The blended composite structure greatly improves toughness and wear resistance compared with pure glass fiber filter bags, avoiding brittle fracture and fiber shedding. It has excellent acid, alkali and oxidation resistance, stably adapting to harsh high-temperature flue gas working conditions such as cement rotary kilns and metallurgical kilns. The dense fiber structure achieves 99.95% high-efficiency interception of 0.3μm ultra-fine dust. Optional PTFE membrane treatment realizes absolute surface filtration with excellent dust release performance, preventing dust embedding and bag clogging. With stable low-resistance operation and super long service life, it is an ideal high-temperature filter material that balances high temperature resistance, corrosion resistance and cost performance.

Key product selling points and advantages.
1. Ultra-high Temperature Resistance, Stable Operation Under Extreme Heat
Adopts special glass fiber blended formula, continuous working temperature up to 260℃ and instant temperature resistance of 280℃. No shrinkage, deformation or strength attenuation under long-term high-temperature flue gas impact.
2. Optimized Blended Structure, High Toughness & No Brittle Fracture
Multi-fiber blended composite improves the defect of pure glass fiber brittleness, greatly enhancing overall toughness and tensile strength. Resists frequent pulse jet impact and hard dust scouring without cracking or fiber shedding.
3. Excellent Acid & Alkali Corrosion Resistance, Anti-oxidation
Inherent excellent chemical stability, effectively resists acidic flue gas, alkaline condensate and oxidative medium erosion. Solves the aging and damage problems of ordinary high-temperature filter bags in harsh flue gas.
4. Ultra-low Thermal Shrinkage, Dimensional Stability & No Air Leakage
Precision blending process controls ultra-low thermal shrinkage rate. The filter bag maintains stable size in long-term high-temperature environment, fits closely with the filter cage without gap air leakage, ensuring complete filtration effect.
5. Optional PTFE Membrane Upgrade, Zero Fine Dust Leakage
Customizable ePTFE microporous membrane lamination realizes absolute surface filtration. Ultra-smooth membrane surface prevents dust embedding, pulse cleaning is thorough, and filtration efficiency is upgraded to 99.95% for ultra-low emission.
6. High Cost Performance & Wide High-temperature Working Condition Adaptation
Better high-temperature and corrosion resistance than FMS filter bags, and more cost-effective than full PTFE high-temperature filter bags. Widely suitable for kiln and boiler high-temperature flue gas dust removal scenarios.
Explanation and answers regarding incomplete dust removal.
Q1：PPS and FMS filter bags cannot withstand ultra-high temperature flue gas above 240℃ and are easy to burn and damage?
EN Solution：Conventional high-temperature filter bags such as PPS and FMS have a maximum temperature resistance of 240℃, and will soften, shrink and fail rapidly in 260℃+ flue gas. Our blended glass fiber filter bag stably operates at 260℃ with instant 280℃ high temperature resistance, no burning or deformation, perfectly solving the problem of insufficient temperature resistance of ordinary filter materials.
Q2：Pure glass fiber filter bags are too brittle, easy to crack and shed fibers during pulse cleaning, causing serious dust leakage?
EN Solution：Single pure glass fiber material has poor toughness and is prone to brittle fracture under repeated pulse impact. Our blended glass fiber filter bag adds high-temperature tough fiber blending, which greatly improves flexibility and impact resistance. It avoids fiber shedding and cracking while maintaining ultra-high temperature resistance, with stable and dust-free operation.
Q3：High-temperature oxidation and acid-base flue gas cause filter bag corrosion, aging and short service cycle?
EN Solution：Ordinary FMS and polyester filter bags are severely corroded by acid-base flue gas and oxidative media. Our blended glass fiber composite material has excellent chemical inertness, resisting acid, alkali and oxidation erosion. The filter structure remains intact for a long time, greatly extending service life.
Q4：Filter bags shrink and deform under high temperature, causing air leakage at the bag mouth and poor dust removal effect?
EN Solution：Most high-temperature filter bags have large thermal shrinkage rate and loose fitting after heating. Our blended glass fiber filter bag features ultra-low thermal shrinkage performance, stable size after long-term high-temperature operation, closely fitting the cage without air leakage, ensuring 100% filtration efficiency.
Q5：A large amount of kiln ultra-fine dust causes filter bag dust embedding and clogging, resulting in high and stable equipment pressure difference?
EN Solution：Unmodified blended fiber felt has rough surface and easy dust embedding. Our optional PTFE membrane composite treatment forms a smooth non-stick surface. Dust floats on the membrane surface without embedding, pulse cleaning is thorough, and the equipment maintains low-resistance operation permanently.
Q6：Full PTFE filter bags are too costly for ultra-high temperature working conditions, while ordinary high-temperature bags are not durable?
EN Solution：Our blended glass fiber filter bag fills the market gap between FMS and full PTFE filter bags. It has higher temperature and corrosion resistance than FMS, and far lower cost than full PTFE. It is the most cost-effective ultra-high temperature filter material for kiln flue gas dust removal, reducing long-term operation costs.
