Publish Time: 2024-07-29
The stability and durability of PET Solvent-Free Release Film in high temperature environments are mainly due to its material properties, production process and special design.
1. Material properties
High temperature resistance of PET substrate: PET (polyethylene terephthalate) is a thermoplastic polyester with excellent high temperature resistance. It has a wide temperature tolerance range, usually between 130°C and 190°C, depending on the film formulation and thickness. This high temperature resistance enables PET Solvent-Free Release Film to maintain stable shape and performance in high temperature environments.
Solvent-free formula: The solvent-free formula reduces the volatilization and decomposition problems that may occur in solvents at high temperatures, thereby improving the stability of the film at high temperatures. In addition, the solvent-free formula also helps to reduce environmental pollution during the production process and meets environmental protection requirements.
2. Production process
Precision control: In the production process of PET Solvent-Free Release Film, process parameters such as temperature, pressure, and speed need to be precisely controlled. This helps ensure uniformity and consistency of the film, thereby improving its durability in high temperature environments.
Special coatings: To further improve the stability and durability of PET Solvent-Free Release Film at high temperatures, one or more layers of special coatings can be applied to its surface. These coatings may have properties such as high temperature resistance, wear resistance, and corrosion resistance, thereby enhancing the overall performance of the film.
3. Special design
Structural design: The stability and durability of PET Solvent-Free Release Film in high temperature environments can be improved through reasonable structural design, such as multi-layer composite or special texture design. Multi-layer composite structure can disperse stress and deformation at high temperatures, while special texture design can increase the surface area and adhesion of the film, thereby improving its high temperature resistance.
Release force control: The release force of PET Solvent-Free Release Film can be precisely controlled as needed. In high temperature environments, stable release force helps to maintain a good separation state between the film and the adherend, avoiding problems such as adhesion or difficulty in peeling.
In summary, PET Solvent-Free Release Film can maintain stability and durability in high temperature environments through the combined effects of its material properties, production process, and special design.
