Flow Medium (Infusion Breather)

Flow Medium (Infusion Breather)

Flow Medium is a reusable, non-woven polyester breather and flow distribution fabric used in vacuum infusion and vacuum bagging processes. It promotes fast, even resin distribution across large laminate areas, dramatically reducing infusion times and the risk of dry spots. After cure, it peels away cleanly to leave a consistent laminate surface.

Key Features

• Fast, uniform resin flow across the entire layup
• Doubles as a breather for effective air evacuation
• Reusable for multiple infusion cycles
• Compatible with all standard resin systems — epoxy, polyester, vinyl ester
• Supplied as a 1500mm wide roll, 50m²

Typical Applications

• Vacuum infusion of large composite panels and boat hulls
• Resin transfer moulding (RTM Light)
• Breather layer in standard vacuum bagging setups
• Distribution medium over peel ply in closed-mould infusion
