Material Properties:
Polyester felt is made of 100% filament polyester fiber. It is produced through a non-woven needle-punched process that ensures uniform fiber distribution. The material undergoes post-processing treatments like singeing, calendaring, or coating, making the surface smooth and resistant to dust blockage. This filter material offers high porosity and excellent permeability, with strong resistance to chemical stability. It is an ideal filter material for solid-liquid separation and filtering both room temperature and corrosive gases.
Key Advantages:
The breaking elongation is less than 20% for MD and 40% for CMD, with low dry shrinkage. It operates efficiently up to 130°C and is a cost-effective choice for various bag house systems. The smooth surface finish reduces running resistance and improves ash removal efficiency, significantly saving energy while maintaining high filtration precision.
- Operation temperature: 150°C
- Maximum surge: 150°C
- Excellent anti-acid, anti-alkali, and hydrolysis stability
- Available Finish: Singed, Calendar, PTFE membrane, W/O

Frequently Asked Questions (FAQ)
1. What is the maximum working temperature for this polyester filter felt?
The material can operate continuously at 200°C and can handle instant surge temperatures up to 220°C.
2. How does the material handle chemical exposure?
This polyester felt offers excellent resistance to acids, alkalis, and hydrolyzation, making it suitable for corrosive environments.
3. What are the available surface finish treatments?
Available finishes include heating setting, antistatic treatment, singeing, calendaring, and PTFE membrane coating.
4. Why is the smooth surface of the filter bag important?
A smooth surface reduces running resistance, prevents dust adhesion, and improves the ash removal effect, which helps in saving energy during operation.
5. What is the breaking strength of this filter cloth?
The material features a high breaking strength of over 6718 N in the warp direction and over 5421 N in the weft direction.
6. Can the size and specifications be customized?
Yes, while we offer regular sizes, the product specifications are fully customizable to meet specific industrial requirements.
