Application:  Tyre industry 

 

         ZC-120HDGR,165HDGR is Granular silica using a special production process,applied to high-performance tires,Dispersed in the rubber with excellent results,superior processing performance,compared with 

the ordinary precipitated silica,with a high filler content,the wet skid resistance,low rolling resistance,heat and wear

resistance,tear resistance,the flexor interference cracking were improved,instead of similar foreign products.
