High-amplifying carbon black. Easily dispersed and provides a high level extrudability of rubber compounds. Includes in the tread rubber of tires for passenger cars and trucks. Provides increased wear resistance tires, high resistance to tensile, tolerable tear resistance. N 220 is recommended for use in the manufacturing of conveyor belts and other rubber products, which require increased durability.
1. Wet granules/dry powder.
2. Used in rubber, plastic industry
3. High quality
Rubber carbon black belongs to black, different from the special carbon black (for ink, paint, etc. ), it's mainly used in the rubber for reinforcing. Generally the use level in the rubber accounted for 20% to 70% of raw rubber. According to the different rubber, the product dosage is different.
Rubber carbon black is divided into several types: High wear resistance: N110, N220, N330, N339, bolt-on: N351, N375, Half a bolt-on: N550 N660, N774, etc. Depending on the purpose of the rubber products, choose different carbon black
Rubber carbon black: N220, N234, N326, N330, N339, N550, N660, N774, N990etc.
Mainly applied to various rubber products such as tyres, rubber overshoes, cable, seal ring, tape etc
We always adhere to the scientific development perspective of improving resource utilization and environment protection, has a complete and scientific quality management system, in the process of producing carbon black, we try to develop new renewable carbon black production equipment continuously.
