Description
Porous PTFE Coated Fiberglass Fabric – 60" Wide
Big Duck Canvas offers premium porous PTFE coated fiberglass fabric manufactured by Hi-Performance Products (HPP). This industrial PTFE fabric combines a woven E-glass fiberglass substrate with high-purity polytetrafluoroethylene (PTFE) resin, providing a smooth release surface with airflow for demanding processing applications.
This lightweight PTFE coated fiberglass cloth features a low-resin construction that preserves porosity through the weave. Its combination of heat resistance, chemical resistance, and release properties supports applications involving composite molding, vacuum bagging, foam curing, and industrial off-gassing.
The fabric measures 60 inches wide, with a standard 100-yard continuous roll length. Supplied nominal properties include a thickness of 0.0023 inches, a weight of 1.75–1.95 oz. per square yard, and a temperature range of −240°F to +500°F.

Frequently Asked Questions
What is PTFE coated fiberglass fabric?
PTFE coated fiberglass fabric is a woven fiberglass textile treated with polytetrafluoroethylene resin. The fiberglass provides reinforcement, while the PTFE coating provides release properties and chemical resistance. This porous grade uses a low-resin construction to retain airflow through the weave.
What is porous PTFE fabric used for?
Typical applications include composite molding, vacuum bagging release cloth, breather and bleeder release systems, foam rubber curing, and off-gassing sheets. It can also serve as raw stock for compatible industrial drying and conveying components.
Can this PTFE coated fiberglass cloth be used for vacuum bagging?
It may be suitable as porous release cloth within a vacuum bagging system. Confirm compatibility with your resin, cure temperature, pressure, and required airflow. Breather and bleeder requirements depend on the complete process and layup.
How wide is the fabric, and what is the standard roll length?
The master roll width is 60 inches (1,524 mm), and the standard continuous roll length is 100 yards. Refer to the product purchasing options for the quantity offered.
What does the 20–120 CFM porosity specification mean?
CFM means cubic feet per minute, a measure of airflow. The supplied nominal range is 20–120 CFM. To compare it with another fabric or a process requirement, confirm the test area, pressure differential, and test method used to obtain the measurement.
Does this fabric have an adhesive backing?
This PTFE fabric is supplied without adhesive backing for mechanical placement in compatible processing applications.
What is the nominal temperature range?
The supplied nominal range is −240°F to +500°F (−151°C to +260°C). Confirm suitability for your exposure duration, chemicals, pressure, and production conditions.
Can I order a sample?
Order a material sample from Big Duck Canvas to evaluate the fabric before purchasing a production quantity.
