F, and T rubber activity and the use of zinc oxide, zinc oxide is difficult to eliminate the use of decentralized weaknesses, good materials scattered throughout the system. Meanwhile they activated curing system as a whole to achieve the activity of curing, curing to increase, curing curve flat, relatively safe process, vulcanized rubber products and greatly improving overall performance.

　　F、T zinc oxide and rubber active agent with the best ratio :

　　F, T/zinc=50/50-60/40 in such cases over the scope and use, and single zinc oxide, apart from the above advantages as well with the most significant following advantages :

　　① T10 long ， T90 (%)=- 4.49 × SaO2 short, mix materials to improve the focus of practice time, and improved plastic raw material processing safety and shorten the curing time and raise the efficiency of production.

　　②Second-aging agent performance;

　　③ raise the NBR oil resistance;

　　④ has also improved the physical properties of vulcanized rubber; ⑤ compound significantly lower costs, and increase product efficiency.
