Application and characteristics: 

Homogenizing agent AU-40 MS improves the homogeneity of elastomers of different polarity and viscosity.

It is rapidly absorbed by the polymers during the mixing cycle. A relatively low viscosity mass is quickly achieved

into which other compounding ingredients can easily be incorporated. The homogenizing agents are particularly

effective with those elastomer blends which tend to crumble at the beginning of the mixing cycle. In most cases, 

AU-40 MS is added to the polymers within the mixing cycle.

The reduction of compound viscosity and "nerve" achieved with AU-40 MS assists further processing.

For instance, bagging tendency can be reduced,extrusion rates are increased without increasing the die swell,

and calendering properties are improved. These benefits are retained even after long storage periods of the

green compounds.

Homogenizing agent AU-40 MS increases the green tack of many compounds although strictly it is not a tackifier. It does, however, boost the efficiency of other tackifying agents. AU-40 MS does not harden during vulcanization. The hardness of the vulcanizate is not reduced as much as when using, for example, mineral oil plasticizers.

Because of its color, AU-40 MS is not suitable for light colored compounds.

Staining may occur under certain conditions.

Homogenizing agent AU-40 MS has good solubility in aromatic and chlorinated

hydrocarbon oils


4 - 15 phr

Package and storage: 

25kgs/bag or as customer’s request;

Stock it well-ventilation dry area below 35℃.Care must be taken not to double stack since the additional pressure will cause storage stability problems. In addition, as with all resins, the material should be used on a first-in, first-out basis.

Shelf Life:2 years from the date of manufacture if stored as indicated above.
