Why Filter Bag Material Matters？Selecting the correct filter bag material is critical for durability, filtration efficiency, and cost-effectiveness. The wrong choice can lead to premature failure, downtime, or safety risks. Below, we break down key materials used in industrial filtration.
1. Nylon (Polyamide)
Pros:Excellent abrasion resistance for slurries with abrasive particles. Good oil resistance (ideal for lubricant filtration).
Cons:Poor resistance to strong acids/bases. Limited filtration precision (5-10 microns). Absorbs moisture (up to 4% in 80% RH), causing pore blockage in humid systems.
2. Polyester (PET)
Pros:Excellent chemical resistance to weak acids (pH ≥4). Handles short-term exposure temperatures up to 150°C . Affordable and widely available.
Cons:Vulnerable to hydrolysis in high humidity. Not suitable for alkaline environments.
3.Polypropylene (PP)
Pros:Resists ≤70% sulfuric acid at 25°C and bases up to pH 14. Hydrophobic: Minimal swelling in water. Low cost, disposable option.
Cons:Low heat tolerance (max 90°C). Poor oil/solvent resistance (swells in hydrocarbons).
4. PTFE (Polytetrafluoroethylene)
Pros:Exceptional chemical resistance (pH 0-14). Withstands extreme heat (260°C continuous). Negligible moisture absorption (≤0.01%).
Cons:High cost and low abrasion resistance. Requires specialized sewing techniques.
5. PPS (Polyphenylene Sulfide)
Pros:Resists organic solvents (ketones, esters). Low moisture absorption (<0.1%).
Cons:
Degrades in >10% chlorine or nitric acid concentrations. Max 95°C in liquids environments (dry use up to 190℃).
Now, you must know how to choose the material for the filter bag.
