DIAPOL WMB
Cold SBR - Carbon Black Masterbatch

DIAPOL - WMB is produced through a process wherein oil emulsion and carbon black slurry, prepared by dispersing carbon black in the water by an intensive mechanical force, are added to SBR latex, and then this mixture is coagulated using only acid and no salts. DIAPOL - WMB therefore, shows the characteristic features of low ash contents, owing to the above coagulating process.

Various advantages that are possessed by DIAPOL - WMB is compared with those compounds prepared by a conventional dry mixing processes are enumerated hereunder:

1) Excellent carbon black dispersion and good processability
2) Mixing time saved through use of banbury mixer and roll mill
3) Saved electric power for mixing
4) Enabled banbury single stage mixing
5) Clean operation at customer's plant by eliminating or reducing the use of free carbon     black
6) Easy stocking of raw materials with a compact storing space and no cold - flowing
7) Easy quality control on final products at customer's plant
8) Low water absorption, excellent resistance against exposure to steam and no metal
    corrosion due to its low ash content

By using DIAPOL - WMB, therefore, customers enjoy various advantages, such as an increase in their present mixing capacity, saving in capital outlay for a new plant, saving in product cost and possible improvement in labor environment, all of which in a single stroke, result in solving various problems inherent in the present rubber industry.
