INTRODUTION
The tread compound filled with N339 has higher reinforcement, abrasion and crack resistance properties than those of N220 compounds, and has good extrusion property. It is very suitable for butyl benzene rubber/butyl rubber compound.
APPLICATION
The application of carbon black N375 is similar as N339, mainly used in the tread compounds of passenger tire, truck tire and cross-country tire.It is also used in coating compounds of conveyor belt, hose and industrial compounds with high abrasion properties.
