Industrial filtration plays a crucial role in various sectors, including manufacturing, energy, and environmental protection. Selecting the appropriate fabric for filtration systems is essential to ensure efficient and reliable operation. This article presents a comprehensive comparison of five commonly used fabrics – PTFE (Teflon), P84, PPS, Aramid (Nomex), and Fiberglass – based on their temperature range, acid and alkali resistance, as well as hydrolytic and oxidation resistance. Understanding the characteristics of these fabrics will assist in making informed decisions when customizing filtration solutions.
Fabric Options and Specifications
- PTFE (Teflon) PTFE stands out for its exceptional temperature resistance and chemical compatibility. With a maximum operating temperature of 250°C (482°F) and ultimate temperature of 300°C (572°F) in transient conditions, it is suitable for demanding applications. PTFE exhibits excellent resistance to both acids and alkalis, making it a preferred choice for corrosive environments. Additionally, it demonstrates outstanding hydrolytic and oxidation resistance, ensuring durability and longevity in filtration systems.
- P84 P84 fabric offers a remarkable balance between temperature resistance and chemical compatibility. It can withstand a maximum operating temperature of 260°C (500°F) and an ultimate temperature of 280°C (536°F) during transient events. P84 demonstrates excellent resistance to acids, while its alkali resistance is moderate. When it comes to hydrolytic resistance, P84 performs moderately, and its oxidation resistance is considered good.
- PPS PPS fabric is valued for its excellent thermal stability and chemical resistance. It can operate at a maximum temperature of 190°C (374°F) and withstand transient temperatures up to 220°C (428°F). PPS exhibits excellent resistance to acids, and although its alkali resistance is moderate, it remains suitable for many industrial applications. The fabric shows moderate hydrolytic and oxidation resistance.
- Aramid (Nomex) Aramid fabric, often referred to as Nomex, provides good temperature resistance and reliable chemical resistance. It can withstand a maximum operating temperature of 204°C (400°F), with an ultimate temperature of 240°C (464°F) during transient conditions. Aramid fabric demonstrates good resistance to both acids and alkalis. In terms of hydrolytic resistance, it performs well, while its oxidation resistance is moderate.
- Fiberglass Fiberglass fabric is widely used for its excellent thermal stability and chemical resistance. It can operate at a maximum temperature of 240°C (464°F) and endure transient temperatures up to 280°C (536°F). Fiberglass fabric exhibits good resistance to acids and alkalis, making it suitable for various industrial environments. It shows moderate hydrolytic resistance but boasts good oxidation resistance.
Comparative Table
The following table summarizes the temperature range, acid and alkali resistance, as well as hydrolytic and oxidation resistance of the five fabrics:
| Fabric | Max. Operating Temperature | Ultimate Temperature | Acid Resistance | Alkali Resistance | Hydrolytic Resistance | Oxidation Resistance |
