Lanmar #66-3 PTFE Coated Fiberglass Fabric (0.003”) is a lightweight porous PTFE fabric engineered for controlled airflow, liquid/gas filtration, and drying applications. Featuring an open-mesh PTFE coating over woven fiberglass, this fabric allows full material porosity while maintaining non-stick release and high-temperature performance from -400°F to +600°F for demanding processing environments. 

This porous PTFE coated fiberglass fabric is ideal for applications requiring efficient air circulation or outgassing of volatile materials. The low-friction PTFE surface with controlled porosity helps minimize product buildup, improve throughput, and extend equipment life in harsh industrial conditions. 

Common Applications

• Air drying and filtering systems

• Composite curing and outgassing mats

• Heat sealing areas requiring airflow

• Industrial HVAC filtration

• Moisture evaporation and drying conveyors

Lanmar #66-3 is available in standard widths and can be custom-fabricated to fit your specific processing or equipment needs.
