A facile way to synthesis insoluble sulfur with high thermal stability by low temperature melting method

In order to prepare insoluble sulfur (IS) with high thermal stability by a low temperature melting method, the factors affecting the IS performance were systematically studied. Stabilizers and curing approaches were also employed to improve the thermal stability for the synthesized IS. The synthesized IS was further treated with a distinctive curing method, and the thermal stability can reach up to more than 54%. Furthermore, the synthesized IS of HD was also compared with commercial product of OT20 from FlexSys Inc. The comparative results showed that the synthesized IS of HD reached the performances of commercial product of OT20 from FlexSys Inc.
