The brief introduction of the vulcanizing agent

The vulcanizing agent can make the rubber molecular chain from the cross linking reaction, the linear molecules to form three-dimensional network structure, lower plasticity, the increase in flexible agent strength material. In addition to the thermoplastic rubber does not need vulcanization, natural rubber and synthetic rubber are to be equipped into the vulcanizing agent for curing. Rubber by vulcanization after the precious value in use, greatly improving the mechanical properties.

 

The vulcanizing agent is inorganic and organic two categories. The former group have sulfur, sulfur monochloride, selenium, tellurium. A class of sulfur-accelerator (such as rubber accelerator TMTD), organic peroxides (benzoyl peroxide), the quinone oxime compounds, polysulfide polymers, urethane and so on.

 

Vulcanizing agents include elemental sulfur, selenium, tellurium, sulfur compounds, peroxides, quinones, amines, resin compounds, metal oxides and isocyanates such as. The most common use of elemental sulfur and sulfur compounds.

 

The vulcanizing agent is applied to all types of natural rubber and synthetic rubber, according to the needs of different vulcanizing agent varieties can be used in conjunction.
