Abstract
Inventia se refera la o compozitie pentru creion termoindicator cu viraj la 100-5 degree C, utilizat la controlul temperaturii în instalatiile si utilajele din industria chimica si industria constructoare de masini. Creionul termoindicator cu viraj la 100-5 degree C este constituit dintr-un amestec de substante termosensibile (complecsi ai cobaltului cu piridina si cu urotropina), material de umplutura (carbonat de calciu) si lianti (parafina si ceara de polietilena). Creionul termoindicator de 100+-5 degree C prezinta un viraj net de culoare de la roz la albastru închis în timp de 2 sec.
