It is generally possible to use a primary amine-containing vulcanization accelerator, a high-promoting low-sulfur semi-effective vulcanization system and a promoter ZBTP. Promising alternatives are hexamethylene-bis-thiosulfate (HTS) or 1,3-bis(citrymethyl)methoxybenzene (BCl) which improve the sulfur and fatigue properties.
Sulfur vulcanization Wikipedia
Sulfur vulcanization is a chemical process for converting natural rubber or related polymers into materials of varying hardness, elasticity, and mechanical durability by heating them with sulfur or sulfur-containing compounds. Sulfur forms cross-linking bridges between sections of polymer chains which affects the mechanical and electronic properties. Many products are made with

accelerator dcbs akrochem datasheet polymer additives
Accelerator DCBS Akrochem datasheetAccelerator DCBS by Akrochem is a delayed action sulfenamide accelerator designed for natural- and synthetic rubber. It provides best scorch resistance and can be used in combination with secondary accelerators. It is suitable for applications where high processing temperature, dynamic stress and exceptionally long flow
An accelerator to sulphur ratio of 5: 1 is typical of an efficient vulcanizing (EV) system where no more than 4 5 sulphur atoms are combined with the rubber for each chemical crosslink. Most of the crosslinks at optimum cure are monosulphidic or disulphidic and only a relatively smafl proportion of the sulphur is wasted in main chain
Sulphur and peroxide vulcanisation of rubber compounds
Abstract Vulcanisation is a process of transforming a plastic rubber compound into a highly elastic product by forming a three-dimensional cross-linked network structure in the rubber matrix. Many systems have been developed to vulcanise rubber compounds, among which sulphur and peroxide curing systems remain the most desirable. The application of

They belong to ultra fast accelerators. They are used mainly during vulcanization of latex systems (e.g. during foam-rubber production) and rubber solutions. Some of them are soluble in water. As they cause very fast vulcanization they are suggested for lower vulcanization temperatures application, the most often from 80 to 110 °C.
