Digital THERMOTAPE® is adhesive tape thermal label which reversibly changes its color and indicates digit at the same time. Green digit shows current temperature. Color changes from Black →Reddish brown→Green→Navy blue as temperature increase. For temperature decreasing, color change occurs in reverse order.

Reference data

Caution

• Crystal display used for Digital Thermo Tape® can be deteriorated by UV and water such as direct sun shine and high humidity and stop changing its color.
• Digital Thermo Tape® is neither acid resistant nor alkali resistant.
• Avoid contact with organic solvent
• Regarding D-50, digit part(reacting part) can become whitish color by heating at 100°C for 10hours. However, product performance is not affected. Also, 2 green temperature indications might appear both in high and low temperature side when temperature is decreasing. In this case, high temperature side shows current temperature.

About us

"From the Ocean to Outer Space"

  NIGK CORPORATION  was fully financed and established by NOF CORPORATION in December 1980. Inheriting the know-how accumulated by TEIKOKU PYROTECHNICS MANUFACTURE CO., LTD., which had lasted from 1938 to 1970, and that of NOF CORPORATION, Kawagoe Plant which succeeded it, we have promoted research and development in various fields in parallel with manufacturing of pyrotechnics and temperature indicating materials and other products. 

  With on ever-expanding scope of our business, our products have been patronized in different fields widely ranging from the deep seabed to outer space, as indicated by our catch phrase, ""From the Ocean to Outer Space,"" contributing to safety and reliability of various systems.

  In order to not only swiftly respond to ever-advancing needs and supply useful products to society, but also ensure safety and reliability, we would like to fulfill social responsibilities as a technology developing corporation and move forward to materialize further development.
