Carbon Black
Our company has a contract partnership with state owned companies, which gives us the opportunity to purchase mostly N550,N660 and N375 type of carbon black from them.
The quality of the carbon black types are determined and set by the United States of America, with a so called ASTM regulation, Certainly, there are also national regulations. There is a huge manufacturing capacity in Eastern European countries (Russia, Ukraine) and there a so called GOST regulation is also acceptable for quality measure.
