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.
Technical Data:
1. Thickness: 25-80 microns as per practical requirements
2. Tensile Strength: CD 26 MPa; MD 23 MPa
3. Elongation: CD 220%; MD 300%
4. Shrinkage: Less than 6%
Advantages:
1. Biodegradable
2. Complete Dissolvability
3. Efficient Mold Release
4. Durability
5. High Temperature Resistance
