on the various roles of 1,3-diphenyl guanidine in silica
the aim of this study was to evaluate the various roles of 1,3-diphenyl guanidine (dpg) in silica-reinforced rubber compounds. two roles of dpg are well known to be: adsorption onto silica surface to reduce the acidic sites and second to boost the silanization reaction as secondary accelerator. however, these two roles are in a way conflicting.

dosage. nitrosamine-generating sulfur donors can be replaced by non-toxic caprolactam disulfide (cld, sulfur donor) or dithio-phosphates (e.g. sdt, sulfur donor plus accelerator) in all common sulfur-curable rubbers using standard, semi-ev (eficient vulcanization) and ev curing systems.
lionac dptt with best price,characteristics and application: ultra-accelerator for nr and synthetic rubber, solid and lattices, particularly nbr in combination with thiazoles, iir, epdm and csm. it is the fastest of all thiurams.
factory price dr a new second-ary accelerator for rubber
several solutions are available to replace dpg like vulcuren or factory price sdt/s. for carbon black filled compounds the new secondary accelerator factory price dr, a polyethylene imine (pei), has been developed. as sulfur and aromatic free chemical this product does not influence the crosslinking density.
technical data sheet (tds) rubber accelerator,application: accelerator dpg is generally used for natural and synthetic rubbers. mainly used in manufacture of tires, slab rubber, rubber shoes and other technical rubber products. package: in woven bag or kraft paper bag lined with pe film bag, net weight: 25kg/bag. storage: stored at room temperature.
accelerators o. sundström ab,fast, non-staining accelerator for both dry rubber and latex applications. low temperature curing can be achieved by the use of tmtd, tetd or dpg as secondary accelerators. mbt confers excellent ageing characteristics to vulcanizates.
- What is accelerator DPG?
- Accelerator DPG is useful as an accelerator/activator for natural rubber, SBR and NBR. It activates accelerators such as MBT, MBTS and sulfenamides. It is a strong secondary for CBTS, BBTS, OBTS, MBT and MBTS. DPG requires the use of zinc oxide and fatty acids. DPG provides satisfactory processing safety and storage stability to rubber compounds.
- Why is DPG used in silica-reinforced rubber compounds?
- Further, while reacting with the silanol groups DPG reduces the polarity of silica by being adsorbed onto the silica surface [, , ]; and finally, DPG is also capable of accelerating the silanization reaction [2,4,7,8]. DPG therefore has turned into a multi-purpose compounding ingredient in silica-reinforced rubber compounds.
- What is accelerator in rubber vulcanization?
- An accelerator is defined as the chemical added into a rubber compound to increase the speed of vulcanization and to permit vulcanization to proceed at lower temperature and with greater efficiency. Accelerator also Decreases the Quantity of Sulphur necessary for vulcanization and thus improving 'aged' properties of the rubber vulcanizates.
- What are bound rubber contents based on DPG concentration?
- Bound rubber contents as function of DPG concentration in the MB; (): total bound rubber; (): chemically bound rubber; (): physically bound rubber. 3.1.3. Silica filler flocculation rate
