It selects and uses high grade oil coke and completed after 1300 Degrees high temperature calcining through 8 fire- Way and 24 calciners.
Product has the following features:
1. It is characterized by less density , Loose texture and porous
2. high carbon, A less volatile, The chemical and physical properties is very stable;
3. And according to the foreign material and product manufacturing, And the strict screening, Have fixed the grain size composition is especially suitable for friction materials and application effect. Size 10- 18, 20- 40, 40- 80 mesh.
4. To reach the technical index of imported products. Friction material used petroleum coke can Lower density, Improve product porosity and compression performance, Thereby improving brake friction performance and stability of comfort and process performance.
