  • Environmentally friendly
What is the shelf life of Nystein's thermal pad gap filler?
The shelf life of thermal pad is depended on its main composition-silicone, which is about 20 years.
How to choose suitable thermal Pad?

First five factors:

1. Thickness

2. Thermal Conductivity/Thermal Resistance

3. Dimensions

4. Breakdown Voltage

5. Temperature Range

Final selection of thermal pad depends on customer’s final design.

What is the thermal pad temperature range?
-55-200℃, the property of main raw material silicone is the major fact to consider working temperature range.
How to choose the thickness and hardness of thermal pad?
Hardness is one of, but not the main consideration for thermal pad selection. Characteristics of the material is the main concern. The proper thickness selection of thermal pad is choosing a pad 0.5 ~ 1mm thicker than actual gap in between the customer's heat source and heat spreader. Unless customer has additional requests, such as floor mats that need harder material, or other SPECIAL requests on hardness, then hardness should be considered.
What is the function of self tacky surface thermal pad?
Our thermal pad is self-tacky, easy apply and re-workable to safe cost and avoid tearing off. Product can be easily removed from or re-applied to the chassis and heat sink for re-work.
