Since thermal management is critical to heat sink performance, testing with Thermex temperature distribution film has become a useful design and assembly quality control check. Thermex, from Sensor Products Inc., is an economical thin sensor film that can be used in virtually any application to test and monitor heated contacting surfaces from 200° to 300°F (93° to 149°C). It can be used alone or in conjunction with Fuji Prescale pressure-indicating film offered by Sensor Products Inc.

Upon exposure to heat, Thermex changes color instantly and permanently to reveal temperature distribution between any two contacting surfaces.
