Silica disperse agent




● Usage


- Decrease mooney viscosity and prevent the tendency of re-agglomerating silica in rubber



● Characteristic


- Improve the property of the rubber and reduce the usage of silan-coupling agent and energy in mixing process.

- Save the cost of manufacturing


* SMD-13

- Mixture of fatty acid and Zinc/Potassium soap. Improve the flow and prevent the re-agglomerating of filler.

- Applicable on any kind of compounds

* SMD-33S

- Mixture of fatty acid and fatty acid soap. Improve the rate of extrusion and sticking of mixing roll

* SMD-53N

- Mixture of fatty acid-amid, not include metal(;Zinc, Potassium and Sodium etc.)

- Specialized to high silica compound. Decrease the mooney viscosity and can keep the mixed compound for a long time
