  • Properties: Excellent vulcanizations agent for natural and synthetic rubber; improve obviously the
    performances of vulcanized rubber in anti-reversion and fatigue resistance. May ameliorate reinforcing
    properties and anti-tearing properties by using Si-69 together with silica white. To improve the dynamic
    performance of manufactured goods and prolong the service life of articles. Having perfect effects on
    semi-efficiency vulcanization system; Non-toxic and non-corrosive.
  • Application: It is suitable for natural and synthetic rubber, mainly used in kinds of rubber products such
    as tires (tires surface or foundation), rubber-roll, conveyer belt surface, agglutination of iron-brush thread,
    cable insulation, cable covering, rubber shoes sole and so on. Usages: Si-69 is added directly into
    rubber compound under mixed abstraction. The normal consumption is 2-5 portions.
  • Packing: In 25/200kgs drums.
  • Storage: Keep container tightly closed in a cool, dry and well-ventilated place, avoiding exposure of the
    packaged product to direct sunlight.
