vulcanization agent an overview sciencedirect topics
vulcanizing agent is the most important ingredient in this system as it is used to strengthen the rubber compound properties through the vulcanization process. normally, this process is conducted by heating the mixture of raw rubber with vulcanizing agents at specific vulcanization time in a pressurized mold.
thermal stability change of insoluble sulfur by a heat,insoluble sulfur (is), used as a vulcanizing reagent of rubber, is prepared by the thermal ring-opening polymerization of sulfur (s8). enhancing its thermal stability and content ratio (yield) is.
- Which vulcanizing agent is used in a rubber compound?
- Three types of the vulcanizing agent are extensively used; the sulphur, insoluble sulphur, and peroxides. After all, sulphur is the most generic vulcanization agent as it is easily available, inexpensive and effectively enhanced the rubber compound (Chandrasekaran, 2007).
- What happens during sulfur vulcanization?
- During vulcanization, the rubber molecule becomes cross-linked and a three-dimensional network structure is formed. During vulcanization rubber loses its tackiness and it is more resistant to solvents, heats, light, etc. Fig. 1.20 shows the schematic representation of sulfur vulcanization. Figure 1.20.
- What is insoluble sulfur?
- h temperature condition 120"Cx15min .Insoluble sulfur is a new rubber vulcanizing agent with which high quality of rubber products can be improved and the defe fur can be made up.Product AdvantageNo blooming during the storage of rubber, keeping the performance of rubber composition to avoid ba
- Which materials can be used as vulcanization agents?
- Organic accelerators and similar compounds that release sulfur at vulcanization temperatures can also be used as vulcanization agents. These materials are added in 3–5 phr and form monosulfidic linkages with excellent heat resistance. The generally used materials are shown in Table 1.17. Table 1.17. Generally used sulfur donor materials
- What is vulcanizing agent?
- Vulcanizing agent is the most important ingredient in this system as it is used to strengthen the rubber compound properties through the vulcanization process. Normally, this process is conducted by heating the mixture of raw rubber with vulcanizing agents at specific vulcanization time in a pressurized mold.
- When was sulfur vulcanization discovered?
- The sulfur vulcanization was discovered in 1839 by Charles Goodyear. During vulcanization, the rubber molecule becomes cross-linked and a three-dimensional network structure is formed.
