Bubble-Free Blue Silicone Protective Film for Electronics and Plate Material

YY0815BLR is a high-performance protective film coated with organosilicon pressure-sensitive adhesive, using premium PET as the base material. It boasts outstanding adhesion capacity and a unique self-degassing design, which can automatically expel air bubbles during lamination to ensure a smooth and wrinkle-free attaching effect. This film can effectively shield protected surfaces from dust, stains, scratches and other contamination throughout the whole process, maintaining the original appearance and quality of products stably.

Constructed with a three-layer structure consisting of PET substrate, silicone adhesive layer and PET release liner, this blue silicone protective film features reliable physical properties. It delivers stable peel adhesion within the standard range, paired with superior tensile strength and good elongation at break, granting it great flexibility and durability. It is not easy to crack or fall off during pasting, processing and peeling, and can adapt to various operating scenarios with stable comprehensive performance.

Widely applicable in the manufacturing, processing, transportation and post-processing stages of diverse products, YY0815BLR serves as an ideal surface protection solution for all kinds of electronic products, including electronic display panels, digital device casings, circuit boards and precision electronic components. Besides electronics, it is also perfectly suitable for surface protection of various plates such as plastic sheets, metal plates, decorative panels and architectural boards. It provides long-lasting effective protection for workpieces during cutting, polishing, assembly and handling procedures in industrial production.

YY0815BLR 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.
