• Operating Temperature Range: -200℃ to +250℃ (with a cracking temperature above 400℃).

Core Characteristics:

Our PTFE filter screens and fabrics are engineered to deliver exceptional performance across demanding applications, with standout features including:

1. Chemical Stability: Resistant to nearly all chemicals, including strong acids, alkalis, and organic solvents—making it ideal for high-temperature, corrosive chemical environments.
2. Thermal Resilience: Operates reliably from -200℃ to 250℃, maintaining mechanical toughness even at -196℃ (with 5% elongation).
3. Low Friction & Self-Lubrication: Boasts an extremely low friction coefficient (0.02, 1/40 that of rubber) and a non-stick surface that prevents adhesion of viscous substances.
4. Durability & Inertness: Exhibits excellent climate resistance (with a long aging life among plastics), physiological inertness (non-toxic, suitable for medical implants), and non-adhesiveness due to its low surface tension.

Applications:

Leveraging its resistance to extreme temperatures, corrosion, and chemicals—including hydrofluoric acid, phosphoric acid, sulfuric acid, nitric acid, hydrochloric acid, and even aqua regia—PTFE products are widely used in:

• Industries: Aviation, chemicals, electronics, bridges, textiles, machinery, papermaking, ceramics, and more.
• Specific Uses: High-temperature/chemical filtering, gas-liquid separation, demisting, and as components in corrosive processing systems. The woven mesh (available in 15–400 Mesh via arrow loom plain weave, diagonal weave, or dense weave) is particularly valued for its reliability in acidic/alkaline media.
