Sulfur coating

Polyperfluorohexane-coated sulfur floats on ethylene glycol for hours, whereas sulfur samples coated with the other two polymers sink after minutes, especially acrylic-acid-coated sulfur. As the surface energy of sulfur after encapsulation with a plasma polymer is brought closer to those of the rubbers, better compatibility with these rubbers is to be expected. [Pg.192]

Table 12 shows the composition of the S-SBR compound used for these investigations. The sulfur used was either unmodified or one of the four samples of polyacetylene-coated sulfur described in Table 3. [Pg.213]

The cure characteristics for the compounds were measured according to the procedure described in Sect. 4.1.2. From the curemeter data shown in Table 13 it becomes clear that the SBR compounds containing coated sulfur show longer scorch times (ts2) and optimal curing times (t90) than the compound with uncoated sulfur. The only exception is for sample PPASg-4, which gives a similar optimal curing time to uncoated sulfur (Sg). [Pg.213]

The vulcanization curves of the SBR-EPDM blends with the various types of coated sulfur are presented in Fig. 33. For all samples, a pronounced increase in the final state of cure (maximum torque) is observed. This demonstrates that S-SBR/EPDM blends cured with plasma-acetylene-encapsulated sulfur provide a better covulcanization behavior. [Pg.215]

The tensile properties of the S-SBR/EPDM blends cured with the uncoated and coated sulfur are shown in Fig. 34. It is clear that the compounds with micro-encapsulated sulfur show largely improved tensile strength, elongation at break, and higher moduli. [Pg.215]

Coating sulfur onto the surface of different carbon materials improves the dispersion of sulfur on the composite materials. The S-coated-MWCNTs are prepared through capillarity behavior between liquid sulfur and MWCNTs. With a low surface tension of 61 mN m, hquid sulfur wets and fills carbon nanotubes... [Pg.820]
