  • What is rubber vulcanization?
  • It is well known that vulcanization is an indispensable process in the manufacture of most rubber products. Typically, a rubber vulcanization system consists of activators (zinc oxide, stearic acid), accelerator (such as thiazoles and sulfonamides), and sulfur [18, 19 ].
  • What is a vulcanization system?
  • Typically, a rubber vulcanization system consists of activators (zinc oxide, stearic acid), accelerator (such as thiazoles and sulfonamides), and sulfur [18, 19 ]. Among them, accelerators play a critical role in adjusting the vulcanization rate and cross-link density of rubber.
  • What are the different types of rubber vulcanizing accelerators?
  • W. He, In rubber tire production, three popular types of rubber vulcanizing accelerators exist that are similar in appearance (i.e., 2-mercaptobenzothiazole, 4,4′-dithiodimorpholine, and tetramethyl thiuram monosulfide).
  • Is sulfur vulcanization still used in rubber industry?
  • Although the vulcanization of rubber has been developed from sulfur vulcanization to organic accelerator vulcanization, but due to the comprehensive consideration of rubber products using sulfur vulcanization and the low sulfur cost, sulfur vulcanization still widely occupies the industrial market [ 11 ].
  • Is ZnO a good activator for rubber vulcanization?
  • Actually, CdO showed better activating behavior in rubber vulcanization [ 38 ], but its higher toxicity precludes its use for substituting ZnO. Therefore, at the moment, ZnO still remains the most efficient activator of rubber vulcanization.
  • Can BTC accelerate vulcanization reaction during the curing process of rubber?
  • To verify whether BTC can accelerate vulcanization reaction during the curing process of rubber, the vulcanization tests of SBR compounds without accelerator CZ (other ingredients were the same as in Table 1) and SBR compound without any accelerator were conducted on a rotorless rheometer at 150 °C.
