Maintaining proper thermal contact across the interface of vacuum and flat web-type machines and lamination presses are among uses for Thermex surface temperature distribution film from Sensor Products, an economical thin film that can be used to monitor heated contacting rollers and presses from 93°C-149°C.
Upon exposure to heat, Thermex changes colour instantaneously and permanently to reveal temperature distribution between any two contacting surfaces. The intensity of this colour change directly relates to the temperature it was exposed to, revealing spot high or low temperature zones and minute surface variations.
Thermex used for testing may be saved for archival purposes, but Sensor Products says its low cost renders it inherently disposable. It can be easily trimmed for smaller applications or custom cut to defined dimensions.
