Maintaining heat within certain parameters between contacting platens and rollers is critical in several converting and printing applications. For that reason, Sensor Products Inc. has developed Thermex^® surface temperature distribution film.

Thermex^® is an economical thin film that can be used in virtually any application to monitor heated contacting rollers and presses from 200° to 300°F (93° to 149°C). Maintaining proper thermal contact across the interface of vacuum and flat web-type machines and lamination presses are among uses for this film.

Upon exposure to heat, Thermex^® changes color instantaneously and permanently to reveal temperature distribution between any two contacting surfaces. The intensity of this color change directly relates to the temperature it was exposed to enabling Thermex^® to reveal spot high or low temperature zones and minute surface variations.

While the used Thermex^® material may be saved for archival purposes, its low cost renders it inherently disposable.  A sheet of Thermex^® which is available in 14” by 17” (35.6 by 43.2 cm) format costs $25.00 or $299.99 for a pack of 25 sheets. It can be easily trimmed for smaller applications or custom cut to defined dimensions.

New applications for Thermex ^®are being discovered daily.  Common applications include heat sealing, lamination/press, converting, metallurgical welding, ultrasonic welding, heat sinking, and clutch/brake interfaces.

Post processing analysis of Thermex^® is available for temperature fluctuations that need to be analyzed with great precision.  For more information or to order Thermex^®, call Sensor Products Inc. 1.973.884.1755 email, This email address is being protected from spambots.
