What are the differences between Glass Fiber Fabric and PTFE Coated Fiberglass Fabric?

Glass Fiber Fabric and PTFE Coated Fiberglass Fabric are related materials, but they have distinct characteristics and applications. Here are the key differences between them:

Base Material:

Glass Fiber Fabric: This is made entirely of woven glass fibers. It is known for its high tensile strength and heat resistance.

PTFE Coated Fiberglass Fabric: It starts with a base of glass fiber fabric, but it is further enhanced by applying a layer of Polytetrafluoroethylene (PTFE) coating. This coating provides non-stick properties and enhances resistance to heat and chemicals.

Non-Stick Properties:

Glass Fiber Fabric: It does not have inherent non-stick properties.

PTFE Coated Fiberglass Fabric: It is inherently non-stick due to the PTFE coating. This makes it suitable for applications where preventing sticking or adhesion is crucial.

Heat Resistance:

Glass Fiber Fabric: It has natural heat resistance due to the properties of glass fibers.

PTFE Coated Fiberglass Fabric: The PTFE coating further enhances its heat resistance, making it suitable for high-temperature applications.

Chemical Resistance:

Glass Fiber Fabric: While it is generally resistant to most chemicals, it may not perform as well as PTFE coated fabric in highly corrosive environments.

PTFE Coated Fiberglass Fabric: It exhibits excellent resistance to a wide range of chemicals, making it suitable for applications where exposure to corrosive substances is a concern.


Glass Fiber Fabric: Commonly used in applications like insulation, reinforcement in composites, and as a base material for various coatings and laminates.

PTFE Coated Fiberglass Fabric: Widely used in applications requiring non-stick surfaces, such as release sheets for baking, conveyor belts in food processing, as well as in industrial settings where heat and chemical resistance are paramount.

Surface Texture:

Glass Fiber Fabric: It has a textured, fibrous surface.

PTFE Coated Fiberglass Fabric: The PTFE coating gives it a smooth, non-stick surface.


Glass Fiber Fabric: Generally, it tends to be more cost-effective compared to PTFE coated fabric.

PTFE Coated Fiberglass Fabric: Due to the added PTFE coating, it tends to be relatively more expensive.

Both materials have their unique strengths, and the choice between them depends on the specific requirements of the application. Glass Fiber Fabric is valued for its strength and durability, while PTFE Coated Fiberglass Fabric is sought after for its non-stick and enhanced resistance properties.

In conclusion, PTFE coated fiberglass fabric is a versatile material that finds applications in a wide range of industries, thanks to its unique set of properties.
