PTFE Film Laminated Glass Cloth is a high‑performance flexible material made by laminating PTFE (Polytetrafluoroethylene) film with E‑glass fiber cloth. It combines the high strength and thermal stability of fiberglass with the superior chemical resistance, flexibility, and non‑stick properties of PTFE, resulting in a lightweight yet durable composite material.

It is primarily used in flexible duct joints for air conditioning and general industrial ventilation systems, and can also serve as an inner lining material for metal tanks. The material effectively absorbs and compensates for pipeline deformation caused by thermal expansion, vibration, and fluctuating air pressure, ensuring reliable sealing performance and extended service life. In tank lining applications, the fiberglass side provides strong adhesion to the metal surface, while the PTFE layer offers a non‑stick, chemically resistant barrier that protects against corrosion and buildup.

Advantages of PTFE Film Laminated Glass Cloth

• Lightweight & Durable: Easy processing, long service life, reduced maintenance.
• Outstanding Chemical Resistance: PTFE film resists acids, alkalis, and organic solvents.
• Mechanical Strength with Flexibility: Combines fiberglass rigidity with PTFE compliance.
• Reliable Sealing: Suitable for non‑metallic expansion joints to prevent gas and dust leakage.
• Dual Surface Functionality: Easy bonding on fiberglass side, non‑stick property on PTFE side.
• Excellent Heat Resistance: Reinforced glass cloth ensures strength and dimensional stability under high temperatures.
