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:

1. Good releasing performance, it barely produces any blanks, which saves polishing time.
2. With high flexibility and smoothness, the PVOH membrane/film can fit the mold better, and the demolding quality is higher.
3. Good heat resistance: the membrane/film can be heated up to 190 degrees.
4. Good mechanical performance: high tensile strength and high breaking elongation rate.
5. Suitable for continuous production, high producing efficiency.

Feature:

1. 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.
2. 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.
3. Surface Protection: In addition to its release properties, PVA release film provides a protective layer for the mold surface. It helps to prevent damage, scratches, or contamination during the lay-up and curing process.
4. Shelf Life: PVA release film has a limited shelf life and can degrade over time when exposed to moisture or high temperatures. It is important to store the film in a cool and dry place, away from direct sunlight and humidity, and follow the manufacturer's recommendations regarding shelf life and storage conditions.
5. Safety Considerations: When working with PVA release film, it is important to follow safety precautions and guidelines. This may include wearing protective gloves and eyewear, ensuring proper ventilation, and handling with care.

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.
