What is Teflon Coated Fiberglass Cloth for Release Membrane
Overview:High-performance Teflon coated fiberglass release membranes for molding, laminating, and curing applications. Factory-direct supply with customizable specifications.
In industrial manufacturing, reliable release materials play a critical role in achieving stable quality and consistent productivity. Teflon coated fiberglass cloth, known for its exceptional non-stick performance, heat resistance, and durability, has become one of the most widely used materials for release membrane applications in composite molding, laminating, vacuum infusion, and thermal processing.
What Is Teflon Coated Fiberglass Release Membrane?
Teflon (PTFE) coated fiberglass is made by applying a uniform layer of PTFE onto premium woven fiberglass fabric.
The result is a high-performance release membrane with:
Excellent non-stick surface
High temperature resistance (up to 260°C / 500°F)
Chemical resistance
Dimensional stability
Long working lifespan
These characteristics make it ideal for environments where materials must not adhere to surfaces during molding or curing.
Applications of Teflon Coated Fiberglass Release Membrane
1. Composite Molding & Vacuum Infusion
Teflon coated fiberglass is widely used as a release membrane in composite manufacturing.
It prevents epoxy, resin, and adhesives from sticking to molds, ensuring smooth surface finishes.
2. Laminating & Heat Press Machines
In laminating applications—such as PCB layers, decorative sheets, or industrial bonding—PTFE fiberglass provides a clean, non-stick interface that improves production efficiency and maintains consistent thickness control.
3. Rubber & Silicone Sheet Curing
During rubber vulcanization or silicone curing, the PTFE membrane ensures easy demolding without residue or deformation.
4. Food Industry Thermal Processing
Food-grade PTFE coated fiberglass is used for baking belts, heat-resistant liners, and non-stick conveyor surfaces.
