Technical Feature
The predispersed masterbatch MBT is a quasi-high-speed, multi-function accelerator which has long vulcanization flat period and endows the vulcanized rubber with good physical and mechanical properties. In the vulcanization without sulfur, the pre-dispersed MBT acts as a scorch retarder. It is used as the vulcanization retarder in the CR material. Alkaline accelerators, like aldehyde amines and guanidines, as well as thiurams and dithiocarbamates accelerators have activation effect on the pre-dispersed MBT.
Processing
Powdery MBT is usually easy to fly and adhere to the devices. It is difficult to disperse evenly during mixing. But the pre-dispersed MBT is easy to mix. It will not agglomerate under normal storage conditions. It has good flowability and there is no dust flying. It blends easily into various rubber materials and disperses evenly. This ensures the optimal activity of the effective ingredient. The pre-dispersed MBT is suggested to add in the late stage of mixing.
Application
A variety of industrial products, such as rubber tubes, conveyor belts, driving belts, cable jacket, etc.
