Description
VAP semi-permeable membrane is a unidirectional breathable film for vacuum assisted process, made of polyurethane (PU) translucent film and nylon fabric. It is air breathable but resin impermeable. Bubbles and volatile components can be continuously pumped away during the entire process, preventing the loss of resin and better improving product performance.
Material | Nylon +PU |
Color | Blue+ white |
Thickness, mm | 0.18±0.03mm |
Unit weight | 120±5 g/㎡ |
Max temperature | 160℃ |
Hydrostatic pressure | ≥8000mmH₂O |
Air Permeability | ≥0.3L/㎡/s |
Application
With the continuous improvement of low viscosity, low exotherm, and thermosetting resin system on manufacturing technology, the core material with good diversion performance, the vacuum resin infusion processing is gradually widely used in composite materials production, so as to achieve the desire of improving FRP product quality, maintaining the integrity of its structure, reducing weight, and reducing overall costs becomes possible. This process has been successfully applied to large wind blades and nacelle covers, train head covers, safety helmets, yachts, ship, sports equipment, etc.Vacuum Infusion processing is a new type of low-cost composite material large-scale forming technology, which eliminates the air of fiber reinforcement materials under vacuum, the use of auxiliary materials can help exhaust excess air, control the resin flow well, achieve impregnation to the fibers and fabrics, so that it can be cured successfully and perfectly.
Packaging and Shipping
1. Store in a cool and dry place, avoid heat, direct
sunlight or rain. Avoid direct sunlight.
2. Storage period: 12 months from the date of
shipment.
3. Avoid direct sunlight. Discoloration does not
affect quality and use.
4. In order to make the cured product easy to
release the mold, the white surface may be
oriented towards the glass fiber, but the
surface cannot be used instead of peel ply.
Width: 0.1m-1.47m
Length:100m,can be customized.
