Breather fabric - Ideal as a semi-permanent, reusable breather pad for vacuum ports .

Features and Benefits 
  • Ensures open airflow in most standard cure cycles, up to 260°C (500°F) at more than 150psi (10.34bars);
  • Port Pads eliminate the need for large bundles of fiberglass, and are reusable;
  • Usually applied in layers of 2 or 3, the Port Pad is placed beneath the vacuum port base and a layer of breather;
  • Port Pad can also be cut into a circle, with a slightly smaller diameter than the vacuum port base, then placed on top of a thin layer of breather;
  • Port Pad will prevent vacuum bagging process materials from entering the ports, while also preventing leaks or vacuum cut-off.
