Properties: P-40,a type of derivative products of P-22,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.

 

Applications: P40 is specially formulated peptiser suitable as mastication aids in a variety of processing conditions for nature rubber or unsaturated synthenic rubber, and should be added at the beginning of 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 best.It can promote the molecular chains to break and reduce the milling time, so as to decrease the cost of rubber prosessing.

 

Storage: Stored closely in a cool,dry, well ventilated area.Avoid exposure to direct sunlight.

 

Package: In 25kg paper bags with prastic inner.
