Durable Polyimide Film Heaters

Description

sing a single-layer polyimide film as the base material, the metal heating layer is directly deposited on the surface by sputtering process, and then cut into a specific heating path by laser. The outer layer is covered with an ultra-thin polyimide coating for insulation. The integrated structure is only 0.08-0.15mm thick, with high bonding strength and strong weather resistance, and can be used for a long time in damp and dusty environments.

Advantages

1.Ultra-thin and lightweight, with a thickness starting from 0.08mm, suitable for precision equipment and ultra-thin interlayers.

2.Resistant to bending fatigue, the resistance change rate is less than 5% after 100,000 ±90° bends, suitable for frequent deformation scenarios.

3.Instantaneous start-up, the response time from power-on to rated temperature is less than 2 seconds, suitable for rapid heating replenishment.

4.Low heat capacity, with the temperature dropping to 50% of the ambient temperature within 3 seconds after power failure, facilitating pulse temperature control.

5.High-frequency compatibility, with dielectric loss less than 0.002 under a 10MHz high-frequency electric field, does not interfere with RF equipment.
