Self-adhesive silicone sheets work continuously inside electronic devices. Their lifespan depends on usage:

1. Low-Power Devices (e.g., watches) – The sheets can last over ten years due to minimal wear.

2. High-Power Devices (e.g., computers) – Due to high heat and continuous operation, they typically last 3 to 5 years.

Proper usage and maintenance can extend their lifespan.
