Specification :

Shandong Bestar Carbon Black Factory, the National Owned Enterprise, produces New Technology Carbon Black. All the exhaust gases generated during the production are exploited to generate thermal power, realized the harmonius unity of economic efficiency and environment protection.

The factory is design 200, 000 tons annual capacity, to be covered in three phases. The second phase has been successfully put into production, annual carbon black production capacity has reached 120, 000 tons. We mainly produce N210, N220, N234, N326, N330, N375, N539, N550, N660, and other various types of rubber carbon black. With excellent product quality, stable production technology parameters, reasonable prices, our carbon black has won praise from customers home and abroad.
