Water-soluble films have been specifically designed to serve as
release agents in the production of solid surface materials,
engineered stone countertops, walls, interior flooring and other
building & construction applications. Our film provides a seamless
release from the mold or casting bed once the product has cured,
enabling a smooth finish while increasing productivity and reducing
labor and waste in the fabrication process.
PVA has excellent performance for making parts of unsaturated
polyester, epoxy resin or other thermosetting resin. It is ideal
for demolding artificial marble, quartz stone and others.
Advantages:
1. BETTER FINISHING
PVA film has perfect releasing performance as it barely produces
any blanks, which saves polishing time.
In addition, because it is a water-soluble it does not leave any
residue behind.
Once the stone product has cured, the PVOH film can be easily
removed by simply running water over the mold.
2. IDEAL FILM
With high flexibility and smoothness, PVA membrane/film can fit the
mold better, and the demolding quality is higher.
Good heat resistance: the membrane/film can be heated up to 140
degrees.
Good mechanical performance: high tensile strength and high
breaking elongation rate.
3. SAFE AND ECOFRIENDLY
It is water-soluble, so it does not leave any residue behind.
It is non-toxic and safe for use with food-grade products.
It is non-flammable and does not produce any harmful fumes.
Water-soluble film can be rapidly degraded into low-element
compounds through the action of natural factors (H2O) to leave no
chemical pollution improving water and land safety. Water-soluble
film belongs to a new type of environmental protection packaging
materials.
