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.

PTFE high-temperature fabric and silicone fabric both use fiberglass cloth as a base but differ in coating material (PTFE resin vs silicone rubber). PTFE excels in non-stick, wear resistance, and chemical resistance up to 260°C. Silicone fabric offers superior flexibility, electrical insulation, and fire resistance (up to 230°C). Choose based on your priority.

PTFE high-temperature fabric offers exceptional chemical resistance, withstanding strong acids, alkalis, organic solvents, and corrosive gases. This article details its resistant substances, limitations (molten alkali metals, strong fluorinating agents), and key factors like temperature, concentration, and mechanical stress.

PTFE impregnation is not limited to fiberglass cloth. This article introduces 7 alternative substrates – aramid, carbon fiber, PBI, porous metal, graphite, asbestos (phased out), and ceramic fillers – with their process features, advantages, limitations, and key applications.

This article explains why alkali-free fiberglass cloth is the preferred substrate for PTFE high-temperature cloth. It covers chemical bonding via silane coupling agents and key physical properties like thermal stability, dimensional stability, and corrosion resistance – ensuring long-lasting performance in harsh environments.
