GLPOLY thermal pad XK-P30--a perfect substitute for Parker THERM-A-GAP 579

Parker THERM-A-GAP 579 is recognised by many customers, what features do it has? Can we find an alternative to parker THERM-A-GAP 579? Let’s take GLPOLY thermal pad XK-P30 and parker THERM-A-GAP 579 for an example to check it out.

Parker parker THERM-A-GAP 579’s hardness is Shore00 30, it means that this product is really soft, it can compress 22% with the forces of 35kPa. The thermal interface materials must be comformable if we request better effect, because the soft thermal pad can cover the product topography effectively even if it is a unflat sureface. GLPOLY XK-P30 thermal gap pad’s hardness is Shore00 40, there is just a small gap comparing with Parker THERM-A-GAP 579, but it is still a conformable thermal pad, it can be compressed by 70%.

Let’s check the thermal performance. Parker THERM-A-GAP 579 is a medium thermal performance thermal gap pad, it possesses 3.0W/mK of thermal conductivity and 0.7℃in/W of thermal resistance. As a professional thermal manangement engineer, we consider that the 0.7℃in/W of thermal resistance is a little high, it is adverse to heat transfer.

GLPOLY XK-P30 thermal pad shows 3.0W/mK of thermal conductivity, but the thermal resistance is much lower than that Parker THERM-A-GAP 579, it is just 0.28℃in/W. By comparisom, GLPOLY thermal pad XK-P30 provides better thermal performance than Parker THERM-A-GAP 579.

For the other features such as electrical insulation and mechanical properties, there are less differences between them because the both of them are silicone based.

In conclusion,  GLPOLY thermal gap pad XK-P30 provides more excellent thermal performance compared with Parker THERM-A-GAP 579, it is a pefect substitute for Parker THERM-A-GAP 579.
