Anti-static PU Protective Film for 3D Curved Glass Protection

The SFY50P01TNJR is a high-performance anti-static PU protective film developed for industrial surface protection applications. Featuring excellent cleanliness, stable adhesion and superior light transmittance, this film leaves no residual adhesive after peeling off from attached surfaces. It also delivers extremely low static voltage during removal, effectively avoiding static damage to delicate materials. With reliable and consistent overall performance, it stands out as a premium protective solution for high-precision industrial processing scenarios.

Structurally, this 60μm protective film adopts a composite design consisting of a 50μm transparent PET film and anti-static polyurethane adhesive layer, matched with a 50μm PET release liner. Compliant with international testing standards, it maintains ultra-low peel strength against steel plates while keeping a light and stable bonding force. The well-designed material structure ensures the film fits closely onto various surfaces without warping or falling off, and guarantees stable physical properties during long-term attachment and subsequent peeling operations.

This anti-static PU protective film is specially engineered for the manufacturing and processing of 3D curved glass, which is widely used in consumer electronics, smart devices, automotive touch panels and display industries. It provides full-surface protection for 3D curved glass in procedures like cutting, polishing, transportation and assembly, preventing scratches, dust contamination and static interference. Its high transparency also allows operators to clearly observe the product status during processing, greatly improving production efficiency and yield rate of finished curved glass products.

Anti-static PU Protective 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.
