Rubber Processing Promoters shortens the mixing time, prolongs the scorch time, improves the flow characteristics of the uncured compound, and serves as a dispersing agent for all fillers. Processing Additives activates the vulcanization due to its Zinc content. An addition of stearic acid is not necessary and a dosage reduction in zinc oxide is possible. With low melting range Processing Promoters is effective in natural and isoprene rubber at low mill temperature. Being rubber soluble, a homogeneous breakdown is achieved without the risk of blooming. Processing Additives has no adverse effect on rubber-to-metal bonding. It improves the storage stability, which is of particular advantage in direct vulcanization.
Used as a peptizing agent, the product should be incorporated at the beginning of the mixing cycle. As dispersant, lubricant or activator, Rubber Processing Promoters should be incorporated together with the fillers.
Dosage: NR, SBR, NBR, IR: 1-3 phr.
EPDM, EPM, HNBR: 2-3 phr.
Rubber Processing Promoters should be stored in cool and dry place. The product can be stored at least two years if storage conditions are suitable.
Processing dispersant and peptizer with Multiple Effects for elastomer compounds. Used for Tire, Technical moulded and extruded articles of all kinds, expanded rubber articles, ebonite.
