About
Perforated Release Film
The perforated release film is used to release the laminate from the vacuum stack following the cure of the component and to control the flow of the resin during the early stages of the component cure, Release films are placed directly in contact With the laminate. Release films are often perforated in order to ensure that any Trapped air, volatiles, or excess resin, which may affect the physical properties of The laminate, can be removed.
We have many types of release films that are available and selection depends on the cure temperature, pressure, and complexity of the component and resin system involved. Release films are often perforated in order to ensure that any trapped air, volatiles, or excess resin, which may compromise the physical properties of the laminate, can be removed. Various perforation patterns are available in a range of film options to satisfy various cure temperature requirements, thicknesses, tensile strengths, adhesion, upper service temperatures, etc.
