The film is made up of the new environmentally-friendly material, PVA/PVOH (polyvinyl alcohol), which is a water-soluble, pollution-free, and non-toxic polymer material. PVA/PVOH is soluble in water and can be fully bio-degraded into water (H2O) and carbon dioxide (CO2) in nature, thus it is a truly environmentally friendly product.
The water-soluble material produced with PVA/PVOH as raw material has a wide range of applications and is suitable for membrane/films/bags in various areas, such as: anti-infection medical fabric bags, anti-infection laundry bags, anti-infection and anti-bacterial laundry storage bags in the field of medicine and health; water-soluble laundry gel membrane/films, preservative wraps for vegetables and fruits, collection bags for pet waste, packing bags for fishing baits in the filed of daily consumer goods; anti-laser embroidery burn-through water-soluble membrane/film/cloth, blank curved surface special-shaped water transfer printing film, artificial marble/artificial limb/silicone mold releasing film, packing bags for pesticides raw materials, detergents, disinfectants, oils, dyes, mineral additives, cement additives, and seed tapes in the field of industrial functional applications.
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:
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.
