Non stick Porous PTFE Film
PTFE film porous type in thickness of 0.03mm is also called peel ply, it has relatively light coating of PTFE in order to keep the material breathable but maintain it's good release feature. Porous PTFE film will allow excess resin, volatiles and trapped air to escape into the breather during curing process. The material can be continuously working in temperature up to 550°F.
● Good permeability
● Provide release from all conventional resin
● Continuous working in temperature to 260℃
● Resist to all chemical corrosion
● Excellent tear resistance
Porous PTFE film also called peel-ply is used in resin infusion processing for aircraft components. This porous Teflon coated glass fabric have a continuous service temperature to 288°C, good permeability allow excess resin and trapped air and volatiles to pass into the breather ply. This PTFE release film just peel off after resin has cured and leaves a very lightly textured surface with very little sanding if any is needed.
