Applications

RF-5

Blend of fatty acid

ester, Zn soaps

and fillers

85-105

whitish pastilles

Acting 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.

PETS

Pentaerythrityltetrastearate

(REACH passed)

55-65

Whitish flakes or powders

PETS 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.

RPA

ZNFA

combination of zinc salts of

higher molecular fatty  acids

selection of zinc salts of

fatty  acids(REACH passed)

97 - 105 °C

97 - 103 °C

light brown pastilles

light brown pastilles

Excellent 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.

LRPA

Blend of zinc salts of

higher molecular, mostly unsaturated fatty acids

75-90

Light brown pastilles

Low 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.
