Vulcanization - an overview | ScienceDirect Topics
In this chapter, a recent study 13 on the network structure of sulfur cross-linked isoprene rubber (IR) is described for natural rubber (NR), in which a new vulcanization mechanism is included. The mechanism was based on the small-angle neutron

The scheme and treatment of the kinetics of scorch-delay vulcanization proposed in a previous paper were applied to natural rubber sulfur vulcanization accelerated by 2,2′-thiobisbenzothiazole (MBTS), 2-(N-cyclohexyl)benzothizaolesulfenamide
Effect of different sulfur content in Natural Rubber mixtures on their thermo-mechanical and surface properties
Keywords—vulcanization, sulfur, natural rubber, additives, cross-links. I. INTRODUCTION By far the most common vulcanizing methods depend on sulfur. Sulfur, by itself, is a slow vulcanizing agent and does not vulcanize synthetic polyolefins.
Crosslinking via sulfur vulcanization of natural rubber and cellulose nanofibers incorporating unsaturated fatty acids
Sulfur vulcanization was 98 achieved by hot pressing at 156 C for 10 min. 99 The chemically modified, CNF-reinforced natural rubber was transparent at a CNF content 100 of 5 wt%, as shown in Figure 4, indicating that the CNFs were well dispersed
Vulcanization Accelerators - CROW
Accelerators for Sulfur Vulcanization of Rubbers Vulcanization of rubber by sulfur alone is an extremely slow process and can take several hours at elevated temperature (140°C or more). This is problematic becasue long exposure to temperature

Vulcanization - Wikipedia
Vulcanization (British: Vulcanisation) refers to a range of processes for hardening rubbers. The term originally referred exclusively to the treatment of natural rubber with sulfur, which remains the most common practice; however, it has also
Benzothiazole - Wikipedia
Benzothiazole is an aromatic heterocyclic compound with the chemical formula C 7H 5NS. It is colorless, slightly viscous liquid. Although the parent compound, benzothiazole is not widely used, many of its derivatives are found in commercial
