How Raw Material Purity Affects PTFE High-Temperature Fabric Performance

Raw material purity is the foundation of PTFE high-temperature fabric performance. High-purity PTFE emulsion (no metal ions, no low-molecular-weight residues) ensures heat resistance (no yellowing up to 260°C), stable non-stick, and high dielectric strength. For fiberglass, alkali-free E-glass (Na₂O <0.8%) maintains strength and insulation at high temperatures; medium/high-alkali glass causes degradation. Complete removal of weaving sizing agents prevents carbonization and delamination. Purity directly affects service life, food-grade compliance, and electrical reliability.

Fiberglass Fabric Pre-Drying: How to Control Temperature and Time Correctly

Proper pre-drying of fiberglass fabric is critical for subsequent PTFE coating, resin impregnation, or lamination. Three main treatments: moisture removal at 105-120°C (10-30 min depending on weight), dewaxing/thermal cleaning at 300-450°C (LOI <0.1%, avoid>500°C), and preheating at 60-100°C before coating. Control oven temperature uniformity (±5°C), forced dehumidification, and protect silane-treated fabrics below 110°C. Store dried fabric in sealed bags or dry rooms (<30°C, <40% RH).

PTFE Tape Salt Spray Resistance & Marine Application Requirements

PTFE high-temperature tape has excellent salt spray resistance, but the weak points are the adhesive layer and the fiberglass substrate edges. Evaluation methods: 1000h neutral salt spray (NSS) test, measuring peel strength retention (≥80% required), visual defects (lifting, blistering), and metal substrate corrosion. For marine and high-salt-fog environments: use silicone PSA (not acrylic), fully impregnated PTFE substrate, seal edges with weather-resistant sealant, and apply primer on metal surfaces.
