Name : Dispergum 24Description: peptizing agentComposition : Highly active oxidation catalyst, combined with zinc salts of defined fatty acids as carrierAppearance : brown* pelletsAnalytical ValuesAsh, 2 h at 950 oC (%) DIN EN ISO 3451-1 : 11.3 - 12.3Dropping point, Mettler-apparatus (oC) DIN ISO 2176 : 108 - 118Density at 20oC (g/cm3) DIN ISO 787 part 10 A : 1.1  Dosage (phr) : 1 - 3German Food Legislation (BfR Recommendation XXI) : not approvedSupply Form : 25 kg in paper bagsStorage StabilityIn originally sealed package in cool and dry places : min. 1 yearBehaviour and EffectsDispergum 24 is a peptizer which disperses rapidly and allows easy incorporation due to its good solubility in rubber. It can be used in a wide temperature range in natural rubber or synthetic polymers such as SBR, BR or others. The duration of the mastication process is drastically reduced by high efficient oxidation catalysts and the supporting effect of zinc soaps. Dispergum 24 is not classified as hazardous material, it does not contain DBD or PCTP.ApplicationFor NR and peptizable SR grades.NotesThe upper surface of the pellets show a varying, mainly lighter colour than the underside, due to cristallisation of the fatty acid carrier.For detailed description of technological effects and dosages see DOG-Kontakt 25.
Name : Dispergum 36Description: Peptizing AgentComposition : Highly active oxidation catalyst, combined with organic and inorganic additivesAppearance : Greygreen pelletsAnalytical ValuesAsh DIN EN ISO 3451-1 : 21.0 - 22.0Softening poing (oC) Kofler method : 58-68Density at 20oC (g/cm3) DIN ISO 787 part 10 :1.3  Dosage  : 01 - 1.0German Food Legislation (BfR Recommendation XXI) : not approvedSupply Form : 25 kg in paper bagsStorage StabilityIn originally sealed package in cool and dry places : min. 1 yearBehaviour and EffectsDue to its solubility in rubber, Dispergum 36 incorporates and disperses with exceptional ease and rapidity. It can be used for NR and SR over a wide temperature range on open mills and in internal mixers. Mastication times are dramatically reduced by Dispergum 36 due to the high efficiency of the oxidation catalyst.ApplicationFor NR and peptizable SR grades, in the necessary dosage.NotesDispergum  36 is not classified as hazardous material.It does not contain DBD or PTCP. For detailed description of technological effects and dosages see D O G-Kontakt 36.
Name : Dispergum 40Description: Peptizing AgentComposition : Highly active oxidation catalyst, combined with organic and inorgainc additives.Appearance : Blue-black pelletsAnalytical ValuesAsh (%) DIN EN ISO 3451-1 : 19.0 - 21.0Dropping point, Mettler-apparatus (oC) DIN ISO 2176 : 92 - 102Density at 20oC (g/cm3) DIN ISO 787 part 10 A : 1.2  Dosage : 0.1 - 1.0German Food Legislation (BfR Recommendation XXI) : not approvedSupply Form : 25 kg in paper bagsStorage StabilityIn originally sealed package in cool and dry places : min. 1 yearBehaviour and EffectsDue to its solubility in rubber, Dispergum 40 incorporates and disperses with exceptional ease and rapidity. Mastication times are dramatically reduced by Dispergum 40 due to the high efficiency of the oxidation catalyst. Composition and melting point of Dispergum 40 are designed specially for mastication in internal mixers at 90-150oC.ApplicationFor NR and peptizable SR grades, in the necessary dosage.NotesDispergum 40 is not  classified as hazardous material.It does not conatin DBD or PTCP.
Name : Dispergum EDescription: zinc soapComposition : Zinc salt of defined unsaturated fatty acidsAppearance : Beige pelletsAnalytical ValuesAsh, 2 h at 950 oC (%) DIN EN ISO 3451-1 : 12.5 - 13.5Dropping point, Mettler-apparatus (oC) DIN ISO 2176 : 78 - 88Density at 20oC (g/cm3) DIN ISO 787 part 10 A : 1.1  Dosage (phr) : 2 - 5 German Food Legislation (BfR Recommendation XXI) : ApprovedSupply Form : 25 kg in paper bagsStorage StabilityIn originally sealed package in cool and dry places : min. 1 yearBehaviour and EffectsDispergum E is a processing additive which acts as lubricant and shows and shows a reducing effect on viscosity. It facilitates mixing and processing, energy can be saved by cooler mixing process and lower viscosities. As an additional effect the dispersion of fillers and other ingredients is improved in NR, SBR and NBR compounds.ApplicationAs a dispersing agent and as mild peptizer in masticatable polyners. Dispergum e is a pure zinc soap of high activity with a particular low dropping point and is therefore suitable for compounding with low shear forces and for open mill mixing. For extruded sections and intricate moulds, microcellular rubber, injection and transfer moulding as well as for soft coumpounds blended in internal mixers.NotesFor detailed description of technological effects of Dispergum zinc soaps and dosages see D O G- Kontakt 31 through 33 and 37More Details.
