How to choose a stainless steel protective film?
Choosing the right protective film for stainless steel is crucial to ensure the material is adequately protected during processing, storage, and transportation. Stainless steel protective films vary not only in thickness and viscosity but also in their protective properties and application suitability. Here’s a guide to help you select the appropriate type:
Transparent Protective Film: This film is typically 50 microns thick and features low viscosity, making it easy to apply and remove. It's ideal for general protection during storage and transport, especially when visual inspection of the steel surface without removing the film is necessary.
PE Blue Film: Also 50 microns thick, this medium viscosity film offers more robust protection against scratches and dirt. It is suitable for situations where the steel might undergo some handling and movement, providing a balance between protection and ease of removal.
PVC Black and White Film: At 80 microns, this film is thicker and provides enhanced durability for more demanding applications. The medium viscosity allows for better adhesion to the metal surface, making it suitable for protecting stainless steel during heavier processing tasks and longer-term storage.
CO2 Laser Protective Film: Designed specifically for use with CO2 laser cutting machines, this 100-micron thick film has high viscosity, ensuring it remains intact during the laser cutting process. It protects the underlying metal from the heat and particulates associated with laser cutting, reducing the risk of surface damage.
Fiber Laser Protective Film: Similar to the CO2 laser film, this 100-micron thick, high viscosity film is tailored for fiber laser cutting machines. It provides excellent protection against the intense conditions of fiber laser cutting, ensuring the stainless steel surface remains unmarred.
