SCIENTIFIC PRINCIPLES

The HEATmarker™ and Fresh-Check® Indicators are a practical application of polymer science.

The TEMPTIME Indicators are extremely sophisticated devices with more than 30 patents based on world recognized science and technology.

• The principle of operation is based on the solid-state polymerization of substituted monomers

• The combined effects of time and temperature cause a gradual, predictable, cumulative and irreversible color change from clear to dark

• The color change follor the polymerization process and is described by the Arrhenius relationship

• The Time-Temperature Indicators (TTI) acts as a warning device to show if the article had been esposed ro excessive heat at any time during storage, distribution and through the final use; they are intended to warn through a visual indicator that a time temperature profile, as specified by the manufacturer of any health products, or by specific users, has been exceeded.
