1. Introduction1.1 Importance of the TopicIn the manufacturing and application of electronic products, high-temperature adhesive tapes play a crucial role. With the rapid advancement of technology, electronic devices are increasingly used in diverse and challenging environments, demanding higher reliability and stability. Temperature resistance, a key performance indicator of high-temperature tapes, directly affects their adhesive properties and functional stability under high temperatures.
Electronic devices often operate in environments with intense heat, such as industrial equipment, automotive engine compartments, or aerospace systems. If the tape lacks sufficient temperature resistance, its adhesion may degrade, causing detachment or displacement, which can lead to component failures and safety hazards. Tapes with excellent temperature resistance ensure stable bonding, insulation, and protection, prolonging device lifespan and reducing failure rates. Understanding the significance of temperature resistance is vital for advancing the electronics industry.

2.2 Impact of Internal Heat on PerformanceExcessive heat within electronic devices can:
● 
Slow down chip processing speeds due to increased electron migration.
● 
Reduce memory读写速度 and battery capacity (accelerated chemical reactions).
●
