3M™ VHB™ Tape 47700 Series is a high-performance adhesive designed to enhance the structural integrity and durability of electronic devices. It offers significant advancements in design flexibility, allowing for stiffer and thinner constructions while increasing usable internal space. With high cohesive strength and dimensional stability, this tape provides up to 80% greater creep resistance than previous models, helping devices maintain their shape and functionality over time — even under extreme conditions such as high temperatures and humidity.
3M™ VHB™ Tape 47700 Series' high performance is validated through rigorous testing, including a 4-point bend test that demonstrates its enhanced flexural strength and resilience against bending forces. In addition to its strength, this tape provides enhanced impact resistance, crucial for the longevity of smartphones and other electronic devices. Specifically, it is engineered to withstand greater impact forces at low displacement levels — as evidenced by shear impact behavioral curves and stainless steel 3-block shear tests — making it ideal for applications where minimizing damage from drops or collisions is essential. These durability features make 3M™ VHB™ Tape 47700 Series a versatile option in bonding applications, helping screen stability and preventing deformation in display bonding, providing strong adhesion for back cover bonding, and offering reliable adhesion and environmental resistance for component bonding, such as camera modules.
