Technical Feature
The predispersed masterbatch MBTS is a universal quasi-high-speed accelerator with good processing safety. It can be used alone or with other accelerators. It can be activated by thiurams, dithiocarbamates and aldehyde amines accelerators. When used together with activated dithiocarbamates accelerators, it can prevent scorch. In the processing and vulcanization of CR materials, the pre-dispersed MBTS has delay effect. The vulcanized rubber obtained by using the pre-dispersed MBTS has goodheat aging resistance.
Processing
Generally, the powdery MBTS is easy to fly and stick on the device, and it is not easy to disperse evenly during mixing. Nevertheless, the pre-dispersed MBTS is easy to mix. It has good flowability and there is no dust flying, so no material loss is resulted in. It will not agglomerate under normal storage conditions. It blends easily into various rubbers and disperses evenly, thus ensuring optimal activity of the effective ingredient, MBTS. It is suggested to add this product in the late stage of mixing.
