grainy black amorphous solids, odorless, specific weight 1.82, burning point beyond 400°c, water insoluble, non-poisonous, stable chemical property.

3.the perniciousness of carbon-black.

nonflammable, explosibility, corrosive, toxicant, radioactive, dangerous nature.

4. production standards.

we strictly fulfill the national standard gb3778-2003 to produce rubber used carbon-black

5. application.

it is used as the strengthening agents and the filling agents for the production of cord layer of tires, sidewall of tires, the rubber material for extrusion or calendered goods.

6.function

n550 fits for nature rubber and all kinds of compound rubber, well disperstiveness , could provide rubber well inflexibility, fast extrusion, and smooth surface after extrusion. swells little, the high temperature stability & heat conductivility of vulcanized rubber are very well. the reinforcing intensity, the elasticity, and the recovering intensity of vulcanized rubber are quite well. it's better to mix with n660 when the n550 was used into butyl rubber (pibi) inner tube.
