YJLG-80/81 is a low-adhesion electronic tape specifically designed for applications requiring gentle bonding and easy peeling. With a peel adhesion force controlled between 30–70 grams, it ensures effective bonding during the encapsulation process while allowing easy removal when needed, leaving no residue—making it particularly suitable for precision component encapsulation that demands high surface cleanliness. The product features a uniform thickness of 0.06mm (tolerance ±0.005mm), maintaining a slim profile while offering excellent mechanical properties—tensile strength ≥2.5kg and elongation ≥30%—ensuring it resists breakage or deformation during high-speed mounting and transportation. YJLG-80/81 provides multiple anti-static grade options: single-sided brown with anti-static performance of 10⁵–10⁸Ω, single-sided light blue with 10⁶–10¹⁰Ω, and double-sided anti-static with 10⁶–10¹¹Ω. Users can flexibly select based on the electrostatic sensitivity of their components. Its standard specifications cover widths ranging from 5.4mm to 97.5mm, and custom sizes are also supported. It is widely used in light encapsulation scenarios such as LEDs and flexible circuit boards, where both adhesion strength and electrostatic protection are critical. | |||||
