INSOLUBLE SULFUR HAVING IMPROVED THERMAL STABILITY AND RUBBER COMPOSITION PRODUCED BY USING THE SULFUR

摘要

PURPOSE: To improve the thermal stability of insoluble sulfur and suppress the blooming of a rubber composition in vulcanization. ;CONSTITUTION: The thermal stability of an insoluble sulfur can be improved by the addition of a small amount of a thiazole compound. The rubber composition is produced by compounding 100 pts.wt. of a rubber with 0.5-10 pts.wt. of the insoluble sulfur.;COPYRIGHT: (C)1994,JPO&Japio
