50μm Silicone Protective Film

This premium silicone-based protective film is constructed with a PET substrate and a high-performance silicone adhesive layer, delivering excellent bonding and air-release properties. It effectively shields surfaces from dust, scratches, and contamination during manufacturing, processing, and handling, ensuring product integrity and quality.

Engineered for reliable performance, this protective film offers stable adhesion, easy application, and clean removal without leaving residue. It is widely used for safeguarding electronic components, panels, and various sheet materials across industrial production and processing environments.

YY0505R polyester film is trusted across multiple high-reliability industries:

• Electrical Insulation – Layer insulation for motors, transformers, generators, and battery packs. Prevents short circuits at high voltages.
• High-Temperature Masking – Used as a coverlay or protective film during solder reflow, wave soldering, and hot bar soldering processes.
• Automotive – Wire and cable wrapping, thermal shielding, and insulation in engine compartments where temperatures exceed conventional material limits.
