PVA Release Film is a water and alcohol-based polyvinyl alcohol (PVA) coating comprised of water-soluble, film forming materials. The dry PVA film is resistant to the solvents in the resin system used to make composites parts but is soluble in water. It is particularly recommended as a parting agent for separation between polyester or epoxy resins and various mold surfaces but may be used with most thermoset resins. PVA Release Film is not recommended for use with resin or substrates containing water or giving off water during cure. PVA Release Film parts easily from mold surface and is readily dissolved from molded parts and spray equipment with water. For most composite casting processes PVA Release Film is used over wax or other mold release agents.
Advantage
1. good detachment performance, easy to produce hair germ after stripping, saving polishing time.
2. with high softness and smoothness, the PVOH film can fit the mold better, and the film removal quality is higher.
3. good heat resistance: up to 190 degrees.
4. good mechanical properties: high tensile strength, high elongation at break.
5. suitable for continuous production with high production efficiency.
6. safe, non-toxic, environmentally friendly and completely biodegradable
Feature:
Water-soluble film is a new type of environmental protection packaging material which is processed by special process and can be rapidly degraded by natural factors (H2O), the water-soluble film can be rapidly denatured, decomposed and degraded into low-element compounds through the action of natural factors (H2O), and has the function of improving land. Water-soluble film belongs to a new type of environmental protection packaging materials.
Water-soluble (PVA) film applicaton:
1. Our water soluble film can be used in detergent packaging, such as dish washing detergent for dish-washing machine, washing powder.
2. The PVA film can help to demould in the production of artificial marble, it can be use for water transfer printing.
3. Our water soluble film is widely used in the agriculture, such as packing the seed and fertilizer.
4. Our water soluble film can be made into all kinds of PVA bag.
