Rubber Compound for Tires — Decomposition

Besides the plasticizer portion (ca. 7%), the first elastomer components during the decomposition of a rubber compound are derived at 383°C (38%) and the second at 448°C (31%). The carbon black portion is calculated at 20% and the ash content at 4%. The position of the peak temperatures of the derived TGA curves (DTG) show that the compound is a carbon black-filled NR/SBR rubber blend. (measurement with TG 209 F1 Libra®)

TG 209 F1 Libra®

Flexibility with the fittings of this premium instrument for thermogravimetry allow it to cover almost any imaginable application in the range up to 1100°C. The system has many outstanding features: BeFlat® function allows or immediate measurement upon switching on the unit, the system’s heating rates of up to 200 K/min allow for faster results, while its corrosion-resistant ceramic furnace withstands even fluorine- or chlorine-containing polymers, c-DTA® function for the detection of exothermal and endothermal reactions.

TG 209 F3 Tarsus®

This easy-to-use instrument for thermogravimetry was developed especially for routine applications in the field of plastics, but also finds application in the chemical industry. With a range of up to 1000°C, it is the ideal starter unit and offers the patented c-DTA® for the detection of exothermal and endothermal reactions with DSC.
