02Battery mounting

With the limited design space in foldable smartphones, selecting the right battery mounting adhesive is essential to balance security, removability, and durability. Our ultra-thin PSA support strong and reliable bonding while maximizing internal space. For manufacturers looking for secure yet removable solutions, our Bond & Detach tapes allow batteries to be easily removed when needed. Additionally, our shock-resistant adhesives enhance overall device durability, ensuring long-term performance even in demanding usage conditions.

03Grounding & Shielding

As foldable smartphones become slimmer, internal components are positioned closer together, increasing the risk of electromagnetic interference (EMI). Our electrically conductive tapes provide high conductivity and gap-filling properties, ensuring effective grounding and EMI shielding. By preventing signal interference, these solutions improve overall device performance, connectivity, and reliability, all while maintaining a compact and lightweight design.

04Display lamination

The durability and clarity of a foldable smartphone display depend on the quality of its optically clear adhesives (OCAs). Our OCAs, produced in cleanroom conditions, ensure crystal-clear visibility while maintaining strong adhesion through repeated folding. Designed for long-term reliability, they enhance display clarity and touch sensitivity, reducing the risk of delamination or distortion over time.

05Thermal management

Managing heat effectively is a key challenge in foldable smartphone design, as compact structures increase thermal loads. Our Thermal Management PSAs offer superior thermal conductivity and heat dissipation, ensuring efficient temperature regulation in slim form factors. These adhesives provide excellent surface wet-out properties, enhancing heat transfer and maintaining stable performance for heat-generating components such as vapor chambers. Unlike conventional adhesives, our solutions prevent overheating and thermal buildup, contributing to a more reliable and efficient device.

07Hinge mounting

The hinge mechanism in foldable smartphones and other devices is a critical structural element that undergoes frequent mechanical stress and exposure to chemicals. Our specialized hinge mounting tapes form a protective seal that prevents adhesive penetration and interface creep, a common issue where adhesive gradually shifts between components over time. 

FAQ

FAQ

Adhesive solutions are ideal for foldable devices because they provide the perfect balance of strength, flexibility, and durability in compact, dynamic designs. These adhesives securely bond components while maintaining a slim profile, essential for the folding mechanism. They also manage heat efficiently, ensuring stable performance, and are flexible enough to endure repeated folding. Additionally, their reworkability makes them ideal for easy assembly and disassembly, supporting the device’s longevity and functionality as it becomes thinner and more complex.

Adhesive tapes offer several advantages over traditional fasteners, including reduced weight, greater design flexibility, and the ability to bond to a wider variety of surfaces. They also eliminate the need for mechanical components that could be prone to wear and tear, leading to a more streamlined, durable device.

Adhesives used in foldable devices contribute to the overall strength and rigidity by bonding components securely. They help maintain the structural integrity of the device, allowing it to withstand the constant folding and unfolding process without compromising strength.

Adhesives improve the user experience by ensuring the smooth function of foldable devices. From providing a secure bond for flexible displays to preventing overheating with effective thermal management, adhesives contribute to the overall performance, longevity, and reliability of the device, ultimately leading to better user satisfaction.
