Achieving Stable and Reliable Bonding in Confined Spaces with High-Performance PET Tapes

As consumer electronics, smart home appliances, and automotive electronics continue to evolve toward thinner and lighter designs, product development increasingly involves complex structures and multi-material assemblies. While thin materials support lightweight design, they are more prone to edge lifting and rebound, and stress concentration becomes more pronounced. These factors pose new challenges to long-term reliability in component fixation and precision bonding.

To address these demands, CROWN New Materials (www.crown.com.cn) focuses on high-requirement bonding applications and has developed a range of high-performance PET tapes. Featuring core properties such as anti-push-out and anti-rebound performance, these tapes deliver stable adhesion across a wide range of applications, ensuring long-term reliability and precise bonding of electronic components.

• Anti-Push-Out High-Performance PET Tape Series

As windows, panels, and similar components continue to become thinner, their fixation and lamination face increasing challenges. During assembly and use, narrowing bezels, reduced structural rigidity, and concentrated stress can lead to edge lifting, rebound debonding, or components being pushed out of position.

CROWN’s anti-push-out PET tape series provides a reliable solution to these issues by offering:

• Extremely high bonding strength, delivering excellent adhesion to glass, plastics, and other substrates;
• Outstanding resistance to push-out, ensuring stable bonding of windows and panels under mechanical stress;
• Excellent die-cutting and processing performance, enabling precise assembly in complex structures;
• Fully transparent design, maintaining structural reliability without compromising optical performance or overall product aesthetics.

• Anti-Rebound High-Performance PET Tape Series

In electronic devices, conventional tapes often struggle to achieve stable bonding on confined surfaces, complex curves, or flexible materials. To ensure long-term reliability in such applications, tapes must provide superior adhesion and strong anti-rebound performance.

CROWN’s anti-rebound PET tape series is specifically designed for these demanding scenarios, offering:

• Very high bonding strength and high initial tack, enabling rapid adhesion to a wide variety of materials;
• Excellent anti-rebound performance, ensuring stable and durable fixation on narrow surfaces, complex curved geometries, and flexible substrates;
• Compatibility with thin and precision assembly requirements, delivering long-term, secure component fixation.

In addition to the anti-push-out and anti-rebound series, CROWN also offers general-purpose high-performance PET tapes, suitable for applications such as cushioning material (e.g. foam) fixation and general component bonding. With a diverse range of performance combinations and proven bonding reliability, CROWN’s high-performance PET tape solutions have been widely adopted across relevant industries and have earned strong customer trust and recognition.

Backed by robust R&D capabilities and comprehensive project management expertise, CROWN is also able to provide customized solutions and end-to-end technical support, continuously empowering customers to drive product innovation and achieve high-quality, sustainable development.
