PVA film can be used as a kind of demolding film with excellent performance when making parts of unsaturated polyester, epoxy resin or other thermosetting resin. At present, PVA film has been widely used in the production of demolding artificial marble. PVA release film is a popular choice in composite manufacturing due to its effective release properties and ease of use. It helps to simplify the demolding process and improve the overall quality of the finished composite parts.
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
