HPP  

Dispersion forcarbon black

Zinc salts of higher molecular fatty  acids

97-105

Light brown

pastilles

Peptizing effect in NR and IR upwards of 60°C. HPP decreases 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. HPP 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.

HST

Dispersion for

silica compounds

Blend of fatty acid

ester, Zn soaps

and fillers

85-105

Light brown pastilles

HST is a dispersion promoter for high loading silica compounds. it shows excellent behavior in silica/carbon black  compounds. HST improves filler dispersion and  reduces mixing and Mooney viscosities. HST increases scorch safety and reduced energy consumption in extrusion. Used in tire, molded and extruded articles of all types, hard rubber.

HT 

Dispersion for

synthetic rubber/CB

Blend of zinc salts of

higher molecular, mostly unsaturated fatty acids

75-90

Light brown pastilles

Low melting processing promoter HT is 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.

HSK 

Dispersion for 

silica  compounds

Blend of fatty acid ester,

Zn soaps and fillers

99-109

Light brown pastilles

Customer specification processing promoter HSK for high loading silica compound dispersion and lubrication. Particularly suitable for silica tire tread and high loading silica rubber articles.

     HTX  

Dispersion for syntheticrubber/CB/Silica

Blend of zinc salts of

mostly unsaturated fatty acids, fatty acid ester,

and fillers

70-94

Light yellow pastilles

Low melting processing promoter HTX is more effective in high loading silica compound  at a mill temperature as low as 60°C. Suitable for low temperature continuous mixing and open mill mixing for silica tire and high loading silica rubber articles.

     H60

    Dispersion for  silica compounds

Mostly zinc soap and fatty acid derivatives

85-95

Light yellow pastilles

Customer specification processing promoter H60 for high loading silica compound dispersion and lubrication. Particularly suitable for mineral filler filled  rubber compounds.

H60EF

Blend of fatty acid derivatives (predominantly zinc soaps).

90-100

Light brown pastilles

H60EF is a newly designed processing additive for applications in natural and synthetic rubber. Due to its selected composition comprising fatty acid derivatives with different polarities,

It provides excellent improvement of processing behavior for a wide range of elastomers like NR, SBR, and EPDM.
