摘要

"Indicating device of integration of time - temperature process to provide an indication of the cumulative thermal exposure of an object, and.The indicator tape viscoelu00e1stica striped "a time temperature indicator provides a visually observable indicator of cumulative thermal exposure of an object.The device includes a substrate having a diffusely reflective to light porous matrix and a support.The support includes on its surface a material indicator memory foam to contact the substrate and a barrier material to substantially inhibit the lateral flow of the viscoelastic indicator materialBetween the substrate and the support.
