What is PTFE coated glass fabric?

PTFE Coated Glass Fabric is a high-performance composite material made by coating fiberglass fabric with polytetrafluoroethylene (PTFE). This combination creates a durable, heat-resistant, and chemically inert material widely used in demanding industrial, architectural, and aerospace applications.

Key Features of PTFE Coated Glass Fabric:

1.Exceptional Heat Resistance

Withstands temperatures from -100°C to +260°C (-148°F to +500°F) continuously, with short-term peaks up to 300°C (572°F).

Non-flammable and self-extinguishing (meets ASTM E84 Class A fire ratings).

2.Chemical & Corrosion Resistance

Resists acids, alkalis, solvents, and most industrial chemicals.

Ideal for corrosive environments (e.g., chemical plants, exhaust systems).

3.Weather & UV Resistance

Does not degrade under sunlight, rain, or ozone exposure.

Commonly used in outdoor structures (e.g., stadium roofs, tensile membranes).

4.Non-Stick & Low Friction

PTFE coating prevents adhesion of sticky materials (e.g., adhesives, food residues).

Reduces wear in conveyor belts and release applications.

5.High Strength & Durability

Fiberglass base provides tensile strength and tear resistance.

Resists abrasion, stretching, and mechanical stress.

6.Electrical Insulation

Excellent dielectric properties for electrical insulation applications.

Common Applications of PTFE Coated Glass Fabric:

Architecture: Tensile structures, stadium roofs, skylights (e.g., PTFE membrane roofs like the Denver Airport).

Industrial: Conveyor belts, release liners, insulation jackets, and expansion joints.

Food Processing: Non-stick drying belts, bakery liners, and packaging equipment.

Aerospace: Heat shields, insulation blankets, and aircraft components.

Chemical Industry: Liners for tanks, ducts, and corrosive fluid handling.

Printing & Textiles: Heat press blankets, dryer fabrics.

Comparison of PTFE Coated Glass Fabric vs. Standard PTFE Fabric:

Cleaning: Use mild soap + water or alcohol; avoid abrasives.

Storage: Keep rolled (not folded) in a dry, cool place.

Inspection: Check for coating cracks or fiberglass fraying periodically.

Why Choose PTFE Coated Glass Fabric?

1.It’s the go-to material for applications requiring:

2.Extreme heat resistance + strength

3.Long-term durability in harsh environments

4.Non-stick, low-friction performance
