PTFE Coated Fiberglass Fabric

Overview

This premium PTFE coated fiberglass fabric uses high-quality alkali-free glass fiber as the woven substrate, combined with advanced PTFE resin formulation. It is processed through imported coating equipment to create a highly versatile composite material. It maintains its physical form without deformation under extreme temperatures ranging from -170°C to +300°C. Approved by FDA and LFGB standards, it is completely safe for food processing and packaging applications.

Data Sheet

Key Features

• Temperature Resistance: Performs reliably from -60°C to 300°C, maintaining strength and flexibility without aging or cracking.
• Non-stick Surface: Easily repels pastes, resins, coatings, and other sticky substances.
• Mechanical Stability: Resists deformation under a compression load of 200Kg/cm² with an elongation rate of less than 5%.
• Electrical Insulation: Features a low dielectric constant of 2.6 and a dielectric loss tangent below 0.0025.
• Chemical Resistance: Highly resistant to almost all chemicals, strong acids, and alkalis.

Product Applications

• Plastic welding and heat-sealing release sheets for the packaging industry.
• High-temperature conveyor belts for drying machinery, sealing, and transferring.
• Electrical insulation for tapes, spacers, gaskets, and high-frequency copper-clad laminates.
• Microwave gaskets, oven liners, and food drying belts for the culinary sector.
• Architectural membrane materials for stadium roofs and exhibition pavilions.

Using Procedure

1. Cutting & Shaping
Use precision cutting tools such as slitting machines, laser cutters, or sharp utility knives to achieve accurate dimensions and avoid fraying the fiberglass edges.

2. Installation & Clamping
Ensure the fabric is laid completely flat without tension wrinkles. For heat sealing applications, secure the edges with appropriate mechanical clamps or heat-resistant adhesives to maintain structural integrity.

Matters Needing Attention

• Folding Restrictions: Never fold or crease the material sharply. Creasing will fracture the internal fiberglass yarns and permanently damage the non-stick PTFE coating. Always store and transport the material in roll form.
• Thermal Degradation: While highly heat-resistant, avoid continuous exposure to open flames or temperatures exceeding 300°C to prevent the release of toxic fumes and thermal degradation of the PTFE layer.
• Storage Conditions: Keep rolls suspended in their original packaging in a clean, dry, and well-ventilated warehouse. Avoid direct mechanical impact or stacking heavy objects on top of the rolls.
