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.
Main Characteristics of PVA film products:
1)Good release film characteristics, convenient demoulding, and subsequent treatment
2)High transparency, easy to check artificial marble surface defects
3)The thickness difference is small and the flatness is high
4)Super wide, can meet the needs of various models in the market
5) Less additives, not easy to deteriorate, dry products can not produce oil
6) Water soluble films for mould release form a barrier between parts and mold surfaces that are still curing
7) An ideal solution in the manufacturing of solid surface materials and engineered agglomerate stone for countertops, bathtubs, construction fascia, indoor flooring, etc
8) PVA films for mould release are also resistant to solvents and yet water-soluble, they can also be customized to meet your specific processing needs
