A Formulação Da Borracha

Different rubber with compounding agents should refer to the basic formula appropriately, as follows
It is very important to study the specific surface area of ​​rubber, main rubber, zinc oxide, stearyl ester, antioxidant, accelerator, sulfur, carbon black, magnesium oxide, and carbon black.
