Advantage:
1. From the performance, not easy to produce, after stripping blanks, save grinding time.
2. With a high degree of softness and smoothness, PVOH film can make a more fitting mold, film of higher quality.
3. Heat resistance: can heat up to 190 degree C.
4. Good mechanical properties: tensile strength, elongation rate.
5. Suitable for continuous production, high efficiency
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.
