Performance and Application: 
Commonly used in natural rubber and multiple synthetic rubbers, generating smooth and medium-speed 
sulphidizing effect with high sulphidizing temperature. 
It offers no coking effect if it isn't working with furnace carbon black. It is easy to operate, disperse, and 
offers no pollution. It can be used in white or color products. Because of bitter taste, it can't be used in food 
rubber. It can be used in the manufacture of tire, rubber pipe, rubber shoes and rubber cloth etc. It also can 
be added into neoprene as retarder or plasticizer.
