Name:Chemical CompositionMelting RangeAppearance/ Supply FormApplications
RF-5Blend of fatty acid ester, Zn soaps and fillers 85-105whitish pastillesActing as one excellent dispersion promoter for high loading silica compounds. it shows excellent behavior in silica/carbon black compounds. RF-5 improves filler dispersion and reduces mixing and Mooney viscosities. RF-5 increases scorch safety and reduced energy consumption in extrusion. Used in tire, molded and extruded articles of all types, hard rubber.
PETSpentaerythrityltetrastearate55-65Whitish flakes or powdersPETS it can effectively prevent the sticking of the compounds to the rubber rolls, and has positive effect regarding the flow and demoulding properties with the injection and mould pressing process, suitable for ACM, H-NBR, EVA, CSM, ECO/CO, IIR/CIIR/BIIR, CR, etc.
RPAcombination of zinc salts of higher molecular fatty acids 97 - 105 °Clight brown pastillesExcellent peptizing effect in NR and IR upwards of 60°C, can decrease the viscosity of compounds based on NR resulting in an easier processing, which leads to higher extrusion rates, better dimensional stability and a stable die swell. RPA provides a good dispersion of the fillers and rubber chemicals in the compound. Used in tire, molded and extruded articles of all types, hard rubber.
LRPABlend of zinc salts of higher molecular, mostly unsaturated fatty acids 75-90Light brown pastillesLow melting-point grade processing promoter, more effective in NR and IR rubber at a mill temperature as low as 60 °C. Suitable for low temperature continuous mixing and open mill mixing for tire, molded and extruded articles of all types, hard rubber.
