Precipitation method white carbon black manufacturer
Precipitation method white carbon black manufacturer introduces the variety and specifications of precipitation method white carbon black
In January 2010, Black Cat Company absorbed the most advanced precipitation white carbon black production technology in China. In Jingdezhen, Jiangxi, three 20,000-ton/year precipitation white carbon black production lines were designed and planned to be completed within three years. The first phase of the project will build a production line of 20,000 tons/year, which will be put into operation at the end of October. Welcome customers to inquire.
Second, the precipitation method of white carbon black varieties:
1. Main varieties:
HM-160
HM-170
HM-180
2. The product variety can be determined according to the specific requirements of the user.
Third, packaging materials and specifications:
1. 10Kg/bag, 20Kg/bag, 25Kg/charter bag, can be transported in bulk, can be coded into a bracket and then transported.
2. Packed in tons of bags.
3. The packaging material is made of kraft paper or PP material, and the film is covered with moisture.
4. It can also be packaged according to the packaging form and specifications required by the customer.
HM-180 product introduction
model | HM-180 |
name | Precipitated silica |
Physicochemical properties | HM-180 is a hydrophilic precipitated silica with a specific surface area of 180 m2/g and is a high purity white powder. |
use | Used in sole materials and rubber products. |
Usage and function | It is used as a reinforcing filler in rubber. It is used in color rubber products instead of carbon black to meet the needs of white or translucent products. It has excellent adhesion, tear resistance and heat and aging resistance. |
