PVA marble release film is a mold release agent used primarily in the production of artificial marble. Made from PVA (polyvinyl alcohol) and other components. This film forms a thin layer on the mold surface to prevent the artificial marble material from adhering to the mold, allowing for easy removal of the finished product while protecting the mold from damage.
Product details:
The PVA film can be used as an excellent release material for unsaturated polyester, epoxy resin, or other thermosetting resin parts. It has the following characteristics:
PVA (polyvinyl alcohol) release film is a commonly used material in composite manufacturing processes. Here is some information about the use of PVA release film:
1. Purpose: PVA release film is primarily used as a release agent and surface protection material in composite molding. It creates a barrier between the composite part and the mold surface, preventing the part from sticking to the mold during the curing process.
2. Release Properties: PVA release film has excellent release properties, allowing for easy removal of the cured composite part from the mold without causing damage or leaving residue. It helps to achieve a smooth and high-quality surface finish on the composite part.
3. Compatibility: PVA release film is compatible with various types of molding materials, including polyester, vinyl ester, epoxy, and other thermosetting resins. It can be used with different mold surfaces, such as fiberglass, carbon fiber, and metal molds.
4. Application: PVA release film is typically applied to the mold surface before the lay-up or infusion process. It is commonly used in conjunction with mold release wax to ensure a release from a composite mold. It can also be used as a barrier in open air gel coat applications.
5. Water Solubility: PVA release film is water-soluble, which means it can be easily dissolved in water after the part has cured and released from the mold. This allows for easy cleanup and removal of the film from the mold surface.

PVA release film is a popular choice in composite manufacturing due to its effective release properties and ease of use. It helps to simplify the demolding process and improve the overall quality of the finished composite parts.
