Core advantages
1. Good highdispersion performance, compatible with silane coupling agents for stable mixing behavior;
2. Lowhysteresis property reduces dynamic heat buildup of rubber compounds, helps balance rolling resistance and wetgrip performance;
3. Balanced rubberreinforcing effect, delivers reasonable abrasion performance for dynamically stressed rubber parts;
4. Stable batchtobatch indicators, suitable for largevolume continuous rubber production;
5. Favorable overall costperformance for tire and general industrial rubber parts.
