Standard Grade PTFE-Glass Fabric
Standard Grade PTFE-Glass Fabric is used in the widest range of applications due to its combination of high performance and moderate price. Applications include release sheets on heat-sealing machines and laminate presses, release surface for paints, adhesives and food products, gaskets, seals and bearings for chemicals, oils, and gases, thermal insulation for high temperature and chemical resistant applications and covers on hot platens, chutes, hoppers and troughs.

Mechanical Grade PTFE-Glass Fabric
Mechanical Grade PTFE-Glass Fabric is preferred in applications where economy is more important than maximum resistance to chemicals and solvents. Applications include chemical resistant laboratory aprons, protective curtains for paint spraying and bottle washing, acid protection and food packaging.

Economy Grade PTFE-Glass Fabric
Economy Grade PTFE-Glass Fabric is designed for large volume applications that require cost-efficiency and high performance. Applications include leaders for processing paper, plastics, metallic foils and cloth, separator sheets for processing uncured rubber and manufacturing of abrasive wheels.

Porous Bleeder & Filter Cloth
Porous Bleeder & Filter Cloth promotes drying by allowing airflow through the fabric. It is used as a release cloth in vacuum molding, filtration, strainers and pollution abatement.


Crease & Tear Resistant PTFE-Glass Fabric
Crease & Tear Resistant PTFE-Glass Fabric is used where high tear strength and good flex life is required, including high speed packaging belts and as edge reinforcement for industrial belts in the packaging and plastics industries.

Tac-Black™ Anti-Static/Conductive
Specially treated fabric that reduces static buildup. It can be provided with carbon loading which offers semi-conductive and anti-static properties.  

Silicone Rubber Coated Fabric
Silicone Rubber Coated Fabric offers a tough coated surface for applications where high flexibility and a high slip coefficient are required. It is an excellent electrical insulator in harsh environments, has high resistance to mild alkali, non-oxidizing acids, most salts, mineral lubricating oil, air, moisture and sunlight and it will release adhesive and viscous materials which often adhere to a fluorocarbon resin. Applications for silicone coated fabric include electrical insulation tapes, gaskets, heater covers, safety curtains, conveyor belts for industrial processes, foam manufacturing, shrink tunnels and release and separator sheets for viscous processes in the chemical, rubber, plastic, electrical and aerospace industries.

PTFE (polytetrafluoroethylene) glass fiber cloth is a high-performance composite material that combines the excellent chemical properties of PTFE and the high strength characteristics of glass fiber. In the aerospace field, it has the following main advantages:

Teflon PTFE Coated Fiberglass Fabric

Excellent high temperature resistance
Spacecraft will face extreme high temperature environments when flying at high speed or returning to the atmosphere. PTFE glass fiber cloth can work stably for a long time at temperatures as high as 200-260℃, and some modified materials can even withstand higher temperatures, effectively protecting the internal structure of the spacecraft from high temperature damage.

Excellent chemical stability
There are many chemical substances in the aerospace environment, such as fuels, oxidants, etc. PTFE glass fiber cloth has extremely strong chemical inertness, hardly reacts with any chemical substances, can resist erosion by corrosive media, and extend the service life of the material.

Low friction coefficient and self-lubrication
PTFE itself has an extremely low friction coefficient (about 0.05-0.1). The use of PTFE glass fiber cloth in aerospace mechanical components can reduce friction and wear between components, reduce energy consumption, improve mechanical efficiency, and reduce maintenance costs.

Good electrical insulation performance
Aerospace equipment contains a large number of electronic components and circuit systems, which require reliable insulation materials. PTFE glass fiber cloth has excellent electrical insulation, can maintain stable electrical performance under high voltage and high frequency conditions, prevent arcing and short circuits, and ensure the safe operation of aerospace equipment.

Lightweight and high-strength characteristics
The combination of the high strength of glass fiber and the lightweight characteristics of PTFE allows PTFE glass fiber cloth to maintain high strength while not increasing the weight burden of the spacecraft. This is crucial for the weight reduction design of aerospace vehicles and helps to improve payload and flight performance.

Weather resistance and anti-aging performance
Spacecraft are exposed to harsh environments such as ultraviolet rays and high-energy particle radiation in space or the atmosphere for a long time. PTFE glass fiber cloth has good weather resistance and anti-aging properties, can resist the influence of these environmental factors, and maintain the stability of material properties.
