Predispersed Rubber Chemicals DOTG-80
Category : Catalyst and Auxiliary/Rubber Auxiliary Agent
CAS NO : EC NO : MF : MW : Packing : 25 kg Product description : Detailed Product Description Manufacturer experienced,Stable , continuable,environmental ISO9001,ISO14001,REACH pre-register.Powder,Granular,Masterbatch HiDispersion® Predispersed Rubber Chemicals DOTG-70 Accelerator for the vucalnization of NR and synthetic rubbers Product description Composition 70% N,N'-di-o-tolyl guanidine, 30% EPDM binder and dispersing agents Appearance Dark grey granules Density,20 oC Approx. ~ 1.10 g / cm3 (20oC) Physiological properties : See safety data sheet (MSDS) Raw material characteristics of DETU: Melting point ~ 171 oC Evaporation loss ≤ 0.5 % CBS content ≥ 96% Sieve residue 63µm ≤ 0.5 % Ash content ≤ 0.5% Use Characteristics The accelerator HiDispersion® DOTG-70 causes very slow onset of cure and a relatively slow rate of cure. HiDispersion DOTG-70, used on its own, causes a strong rever- sion; therefore the use of effective antioxidants is recommended. When HiDispersion DOTG-70 is used in combination with mercapto, sulphenamide, thiuram and dithiocarbamate accelerators, reciprocal activation and secondary acceleration can be achieved. The crosslinking density and rate of cure are increased. Good mechanical properties and good ageing resistance are obtained. HiDispersion DOTG-70 has no tendency to bloom in the vulcanizates. Processing Advantages The thermoplastic, excellent compatible EPDM/EVA binder which is combined with active dispersing promoters allows much more easily and quickly incorporation and excellent dispersion in the rubber mixing. In this way, optimal activity of the effective DOTG is assured. Dosage levels In NR primary: 0.8 - 1.2 phr DOTG-70 with 2.5 - 4 phr S-80; secondary: 0.05-0.4 phr DOTG-70 with 1-1.5 phr MBTS-80 and 1.5-3 phr S-80; In SBR 0.1 - 0.4 phr DOTG-70 with 1 - 1.5 phr MBTS-80 and 1.5 - 2.5 phr S-80; In NBR 0.05 - 0.4 phr DOTG-70 with 1.5 - 2.4 phr S-80 and 0.8 - 1.5 phr CBS-80.
