mixture batches.
2. Improve the flowing of the compound, allowing the compound mixing uniformly. Especially suitable
for the rubber extrusion and injection molding processing. The extruded compound surface is smooth
and has no air holes.
3. Decrease the Mooney viscosity rapidly, and shorten the rubber mixing time.
4. Improve the foaming of EVA products and the uniformity of foam.
Usage:
Add in together with filling agents.
