PVA film is mainly used for demoulding artificial marble and as release film. In the production process of marble, the water-soluble film is placed inside the mold film to quickly demould. A polyvinyl alcohol release film for artificial marble molding, which is a release film disposed between the original liquid and the shaping device when the original liquid which is a raw material of artificial marble is supplied to the shaping device and cured for molding, is characterized in that the release film is provided in the manufacturing of a wide range of artificial marble, and can suppress wrinkles, curls, and the like generated at both ends, and prevent the surface shape of the resulting artificial marble from being poor, the steps of grinding and grinding the artificial marble can be simplified.
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
