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.
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
