PRODUCT INTRODUCTION OF N-660

1. Package
1.1 The packages of 20Kgs, which were made of PP material or Kraft papers.
1.2 The packages of 500kgs /1000kgs, which were made of PP material
1.3 Special specifications on the package are acceptable.

2. The Physical & Chemical property.
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, inner tubes, bicycle tires, rubber tubes, rubber tapes, cable ropes, shoes kind, and patterns.

6. Function
N660 fits for all kinds of rubber. Compared with half-reinforcing carbon-black, N660 has more complicated structure, smaller particles, and higher disperstiveness. The tensile strength, the tear resistance, and the tensile stress at a given elongation of vulcanized rubber are very high. Deformed little, heat rise slowly, well elasticity and good flex resistance, but the tensile stretch is low
