Materials
Filter bags manufactured by F4T are made from high-quality filter media, carefully selected from recognized suppliers. A rigorous supplier evaluation and control process allows us to guarantee consistent product quality as well as good availability of different filter media and controlled delivery times.
The basic materials used for manufacturing filter bags include the following woven fabrics and needle felts:
| Materials | F4T Code | Operating Temp °C | Peak Temp °C | Flame Resistance |
|---|---|---|---|---|
| Polypropylene | PP | 90 | 100 | Yes |
| Acrylic homopolymer | HA | 125 | 135 | Yes |
| Polyester | PE | 140 | 160 | Yes |
| Polyphenylene sulfide | PS | 190 | 210 | Yes |
| Meta-aramid | MA | 200 | 220 | No |
| Polyimide | PI | 220 | 240 | No |
| Polytetrafluoroethylene | TF | 240 | 260 | No |
| Fiberglass | GL | 260 | 300 | No |
| Materials | F4T Code | Acid Resistance | Alkali Resistance | Oxidant Resistance | Solvent Resistance | Hydrolysis Resistance |
|---|---|---|---|---|---|---|
| Polypropylene | PP | Excellent | Excellent | Acceptable | Acceptable | Good |
| Acrylic homopolymer | HA | Good | Acceptable | Good | Good | Good |
| Polyester | PE | Good | Acceptable | Good | Good | Poor |
| Polyphenylene sulfide | PS | Good | Good | Poor | Good | Excellent |

Treatments
Filter media can be enhanced with specific treatments, adapted to operating conditions and process constraints. Among the most commonly used treatments are:
| Treatment | Description |
|---|---|
| Calendering | Facilitates cleaning (dust release) |
| Singeing | Increases abrasion resistance |
| PTFE Membrane | Reduces fine dust emissions |
| Hydrophobic and/or oleophobic | Increases resistance to acids and alkalis |
| Antistatic | Prevents explosion risks |
| Flame retardant | Protection against incandescent particles |
