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, quartz stone and so on. At present, we mainly export demoulding film to Korea, Vietnam, Italy and Canada.
Product details:
The PVA film can be used as an excellent release material for unsaturated polyester, epoxy resin, or other thermosetting resin parts. It has the following characteristics:
PVA (polyvinyl alcohol) release film is a commonly used material in composite manufacturing processes. Here is some information about the use of PVA release film:
1. Purpose: PVA release film is primarily used as a release agent and surface protection material in composite molding. It creates a barrier between the composite part and the mold surface, preventing the part from sticking to the mold during the curing process.
2. Release Properties: PVA release film has excellent release
properties, allowing for easy removal of the cured composite part
from the mold without causing damage or leaving residue. It helps
to achieve a smooth and high-quality surface finish on the
composite part.
3. Compatibility: PVA release film is compatible with various types
of molding materials, including polyester, vinyl ester, epoxy, and
other thermosetting resins. It can be used with different mold
surfaces, such as fiberglass, carbon fiber, and metal molds.
4. Application: PVA release film is typically applied to the mold
surface before the lay-up or infusion process. It is commonly used
in conjunction with mold release wax to ensure a release from a
composite mold. It can also be used as a barrier in open air gel
coat applications.
5. Water Solubility: PVA release film is water-soluble, which means
it can be easily dissolved in water after the part has cured and
released from the mold. This allows for easy cleanup and removal of
the film from the mold surface.
.
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.
