Application and characteristics:

AURORA homogenizing agents improve the homogeneity of elastomers of different polarity and viscosity. They are 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. The softening viscous resins wet the surface of the crumbs promoting the formation of a compact mass.

The reduction of compound viscosity and "nerve" achieved with AURORA homogenizing agents assist 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.

AURORA homogenizing agents increase the green tack of many compounds although strictly they are not tackifiers. They do, however, boost the efficiency of other tackifying agents.

AURORA homogenizing agents do not harden during vulcanization. The hardness of the vulcanizate is not reduced as much as when using, for example, mineral oil plasticizers.

Homogenizingagent AU-40MS FLAKES is a mixture of dark, aromatic hydrocarbon resin which has a very good compatibility with most standard elastomers, such as SBR, NR, NB,CR, IIR, BIIR, EPDM and BR and is used in elastomer blends and homopolymer,compounds. Blending of elastomers with different polarities and/or viscosities are significantly facilitated.  In particular difficult to process tire tube and innerliner compounds have been significantly improved with AURORA 40 MS FLAKES.

Because of its color, AURORA 40 MS Flakes is not suitable for light colored compounds. Staining may occur under certain conditions. Where non-staining is specified, AURORA 60 NS Flakes should be used.

In most cases, the homogenizing agents are added to the polymers within the mixing cycle.AURORA 40 MS Flakes and AURORA 60 NS Flakes have good solubility in aromatic and chlorinated hydrocarbons.

DOSAGE:

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.
