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.
Characteristics
1. Efficient Mold Release: Ensures good mold release performance, reducing burrs post-stripping and saving time on grinding processes.
2. Quality Enhancement: Offers good softness and smoothness, preventing wrinkles and curling, ultimately resulting in high-quality solid surface finishes.
3. High Heat Resistance: Withstands temperatures up to 150°C, maintaining integrity during the molding process.
4. Robust Physical Properties: Exhibits large tensile strength and high elongation rates, contributing to durability and performance consistency.
5. Production Efficiency: Suitable for continuous production processes, enhancing overall production efficiency.
