Breathers & Bleeder
The breather /bleeder layer is usually a non-woven fiber material that avaible in a variety of thicknesses and/or weights. Its main purpose is to give a continuous air passage for extracting vacuum on the component under ambient pressure. Due to the pressure and wrinkles in the vacuum bag, it traps air and the breather fabric prevents and facilitate this from happening. The Breather will also absorb excess resin bleeding through the perforated release film. As the bleeder has no release capability, it is higly reccomanded to use a release film against the component.
- Better air extraction properties.
- Avaible in wider widths
|Maximum use temperature||205°C|
|Shelf life||Unlimited at 22°C|
Breather Fabric has no release characteristics and should be separated from the laminate by a suitable porous release fabric or film.
