Coating uniformity of PTFE high-temperature fabric is determined by four factors: coating formulation (particle size 0.15-0.35 μm, viscosity, solid content), coating & sintering process (blade coating preferred for uniformity), substrate quality (weave pattern, pre-treatment), and production environment (20-25°C, <60% RH). Dip + blade combined process balances penetration and surface smoothness.

Proper cleaning and maintenance extend the life of PTFE high-temperature fabric. Clean after use and after cooling. Use soft brushes, neutral detergents, or alcohol for stains. Never use strong acids/alkalis, bleach, or metal scrapers. Regular silicone oil lubrication reduces wear. Follow these guidelines to prevent coating damage.
