Carbon black - N660

Dry carbon black N660
Product property
Mainly adopt coal tar oil as raw material , belong soft carbon black product,compare with semi-reinforce carbon black , it with polymer structure, Smaller particles,easy to disperse , tensile strength and tearing strength ,modulus of vulcanizate is high,while with small deformation,low heat of formation, good at elasticity flex stiffness
Range of application
Mainly use in cord ply of tyre,inner tyre ,bicycle, rubber hose , adhesive tape,electric cable ,shoe and rolled products etc.
