Frequently Asked Questions about thermal conductive adhesive

1. What is thermal gel?

Thermal conductive adhesive is a bonding or gap-filling material that transfers heat from electronic components to heat sinks or device housings while providing mechanical support.

2. How do I select the right thermal conductivity?

Estimate power loss, allowable temperature rise, and interface thickness. Higher power density or thinner gaps usually need higher thermal conductive to keep devices within safe limits.

3. What is the difference between grease, pad, and gel?

Thermal grease offers low resistance but can pump out. Thermal pads are solid sheet materials that are easy to install and resistant to aging. Thermal gel provide good conformity, low stress, and better long-term stability.

4. Which tests are most important for automotive and EV use?

Key tests include thermal cycling, high-temperature storage, vibration, electrical insulation, and chemical resistance to ensure safe and long-lasting performance in harsh conditions.
