- How does insoluble sulfur affect the performance of rubber compounds?
- At 130°C, there is no significant dif-ference in the rate of migration between insoluble and soluble sulfur. The use of insoluble sulfur can pre-vent sulfur migration between adjacent rubber compounds thus avoiding varia-tion in compound performance. Table IX. Processing and curing properties. Effect of HD OT 20.
- Is sulfur soluble in rubber hydrocarbons?
- To and Arie De Hoog Ordinary sulfur used for rubber com-pounding is in the stable, rhombic form, which is soluble in rubber hydrocarbons at processing and vulcanization temper-atures. As temperatures rise during mixing, more sulfur is dissolved in the rubber. Fig. 1 gives the solubility of sul-fur in several polymers.
- How is the thermal stability of a polymer sulfate determined?
- Since the thermal stability of IS is considered to be closely related to the chain length of polymer sulfur, a method for determining the chain length of IS was investigated by quantifying the amount of electron spin of radicals from sulfur, estimated from electron spin resonance (ESR) measurements.
- What happens if sulfur is exposed to high temperatures?
- When insoluble sulfur is exposed to higher temperatures (greater than 40°C) for long periods of time, it will convert to the more stable soluble rhom-bic form. In addition, exposure of insolu-ble sulfur to certain basic materials, such as amines, also will convert it back to the soluble form of sulfur.
- Should insoluble sulfur be kept away from basic Ma-terials?
- During storage, insol-uble sulfur should be kept away from these materials. To demonstrate the effect of basic ma-terials, the following experiment was carried out. Four ounces (50 grams) each of sulfenamide accelerator, TBBS and insoluble sulfur were placed in sep-arate polyethylene bags.
- How to improve the thermal stability and content ratio of is?
- Enhancing its thermal stability and content ratio (yield) is important for the industrial production of IS. The post-heating process at a high temperature of 70 or 90°C of the mixture of IS and S8 enhanced the thermal stability of IS and reduced the yield of IS. Further, the process at 30°C enhanced its thermal stability and maintained its yield.
