- 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.
