Compared with traditional powdered CaO, Actmix® CaO-80 has the following advantages:
Raw materials 38µm are all under sifting, but no dust appears with master batch
master batch CaO-80 is wrapped with rubber carrier, and thus can effectively ensure the activity of CaO.
No clay domain appears with master batch at room temperature
Has low Mooney viscosity at low temperature such as 50°C to improve disperse quality
While granulation, master batch can filtering to lower rejection rate.
Has good compatibility with different rubbers |
