Vacuum Port Pads are made of a coated mesh. The Port Pad eliminates the potentialfor airflow constricting compaction of the polyester breather under the vacuum port in a composite part process lay-up. The open mesh construction permits easy flow of air from the breather through the vacuum port to the vacuum hose.
The coated mesh, which has 75% open area, is constructed to provide a rigid ventilating structure.
The coating material is highly resistant to most chemicals and solvents used in the manufacturing process for fiber reinforced composites, and has an operating temperature capability of 550°F.
Port Pads are nominally 3” x 3” x .10” thick (approximate) are put up in packages of 25.
Custom sizes are available upon request.
