Properties: A86, is non-dusting blue flake .Compared with powder peptizers ,it can be suitable to be weighted automatically, so as to improve the operating environment greatly while making better the processability. The product has no harmfulness when used normally, and the storage is stable under the condition of low temperature and dry.
Application: A86 is specially formulated peptiser suitable as mastication aids in a variety of processing conditions for natural rubber or unsaturated synthetic rubber, and should be added at the beginning of the mixing cycle, internal mixers or open mills. It can enhance the milling efficiency evidently at processing temperature over 70,and at 150 to 160,the effect is the best. It can promote the molecular chains to break and reduce the milling time, so as to decrease the cost of rubber processing.
Recommended dosage is 0.1 to 0.5 phr.
storage: Stored closely in a cool, dry, well-ventilated area. Avoid exposure to direct sunlight.
