Key Technical Features (Why Choose Us)
Precision Die-Cut: Strict tolerance control (±0.1mm) guarantees a perfect fit for specific phone models without manual trimming.
High Bond Strength: Utilizes modified acrylic adhesive that provides 1.2+ kgf/inch peel adhesion, preventing the back cover from loosening due to heat or impact.
Excellent Conformability: The 0.1mm ultra-thin substrate fills micro-gaps between the frame and glass back, reducing breakage risks during press-fitting.
Temperature Resistance: Stable performance from -20°C to 80°C, maintaining adhesion after wireless charging heating cycles.
Clean Removal: Leaves no sticky residue when reworked, protecting expensive OLED screens and internal components.
