Thermo-gravimetric technology was used to rapidly evaluate and measure safe use life of food contact polymer materials. The thermo-gravimetric curve showed that silicone rubber pad decomposition temperature was about 350°C in air and the maximum decomposition rate was 450°C. 370°C, 380°C, 390°C, 400°C, 410°C at the right temperature zone was chosen to do thermo-gravimetric constant temperature experiments; the time of silicon rubber pad’s weightlessness of 5%, 10% 15% was calculated by the above curve, respectively. Finally Arrhenius equation was used to establish the relationship between temperature and time; and then the result of infer silicone rubber pad using life was 1.37 thousand times when it was used as a baking tray.
