The micro-scale thermo-gravimetric results show that pyrolysis kinetics of waste tyres can be regarded as the linear accumulative total of each elastomer (NR, BR or SBR) as well as their process oils, and the range of reaction is from 250℃ to 520℃, which implies that the kinetics is rarely dependent on the heating.

In this article,oil based adjuvants including petroleum oils,vegetable oils and their derivatives were introduced:their mode of action,verities and applications in herbicides.
