PVA marble release film is a mold release agent used primarily in the production of artificial marble. Made from PVA (polyvinyl alcohol) and other components. This film forms a thin layer on the mold surface to prevent the artificial marble material from adhering to the mold, allowing for easy removal of the finished product while protecting the mold from damage.

Characteristics:

Efficient Mold Release: Ensures good mold release performance, reducing burrs post-stripping and saving time on grinding processes.

Quality Enhancement: Offers good softness and smoothness, preventing wrinkles and curling, ultimately resulting in high-quality solid surface finishes.

High Heat Resistance: Withstands temperatures up to 150°C, maintaining integrity during the molding process.

Robust Physical Properties: Exhibits large tensile strength and high elongation rates, contributing to durability and performance consistency.

Production Efficiency: Suitable for continuous production processes, enhancing overall production efficiency.

Technical Data:

Thickness: 25-80 microns as per practical requirements

Tensile Strength: CD 26 MPa; MD 23 MPa

Elongation: CD 220%; MD 300%

Shrinkage: Less than 6%
