Peptiser Accimel E
Accimel E is used as a peptiser for natural and synthetic rubbers. It disperses readily and can be added to the rubber on open roll or in internal mixer. Its use improves mill room productivity with improved dispersion of fillers.
Being based on DBDS it is viewed as a preferred peptiser for radial tyre compounds. Typical dosage in NR varies from 0.2 - 0.5 phr while higher dosages eg 0.5 - 1.0 phr are required in synthetic rubbers.
