Durable Water Soluble Release Film With Temperature Resistance 170C-180C

Durable Water Soluble Release Film With Temperature Resistance 170C-180C

Product Description:

PVA water soluble release films are designed to aid in the fabrication of solid surface materials and engineered agglomerate stone for countertops, sinks, bathtubs, vertical and horizontal construction fascia, indoor flooring, wall construction and other applications. The unique adhesive release characteristic of our solid surface water-soluble films ensures the product can be easily released from its mold or casting bed after the composite has cured, leaving a smooth finish. Compared to alternative liquid mold release materials, pva water-soluble films reduce the production cost of finished goods by reducing labor and utilities, increasing yields and simplifying waste management. We can also customize film characteristics to meet your specific processing needs.

Features:

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.
6. Surface Protection: In addition to its release properties, PVA release film provides a protective layer for the mold surface. It helps to prevent damage, scratches, or contamination during the lay-up and curing process.
