TMI 1592 Edge Breather/Vacuum Port Pads are made of a Polytetrafluoroethylene (PTFE) coated fibreglass mesh in a bonded stack of 3 layers, bonded with a coated layer of hot melt PTFE adhesive centred between the layers. 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 has a warp of 5 – 6 per inch and a weft of 5 – 6 per inch. The mesh is constructed to provide a rigid ventilating structure ideal for autoclave processes and has a weight of 10 ounces per square yard. The coating material is highly resistant to most chemicals and solvents used in the manufacturing process for fibre reinforced composites and has an operating temperature capability of 550°F. Edge Breather strips and Port Pads are approximately 0.10”thick and are available in a variety of widths and lengths.
