Rubber Predispersed Masterbatch NOBS-70

Technical Feature
The predispersed masterbatch NOBS-70 extends the scorch time of the rubber materials and makes the vulcanization safer. It can be used separately as the primary accelerator in low-sulfur vulcanization. Or it can be used together with dithiocarbamates or thiurams accelerators. The scorch time of the rubber is greatly reduced and the obtained vulcanized rubber has excellent heat aging resistance and good compression set.

When the pre-dispersed NOBS-70 and thiuram TMTM-70 are used together, the vulcanization time is significantly shortened and there is good anti-scorch effect as well as high degree of crosslinking. In low-sulfur rubber materials as well as rubber materials containing thiols accelerators, the pre-dispersed NOBS-70 can delay scorch.

Processing Advantage
The powdery NOBS is usually easy to fly and adhere to devices. It is not easy to disperse evenly during mixing. But the pre-dispersed NOBS-70 is easy for mixing. It will not agglomerate under normal storage conditions. With good flowability, there is no dust flying and no material loss caused. The optimal activity of the effective ingredient, NOBS, is ensured due to the quick blending into various rubbers anduniform dispersion. It is recommended to add the product in the late stage of mixing.
