dpg or n, n'-diphenylguanidine is normally characterized as a secondary accelerator for natural rubber and styrene butadiene rubber (fig. 1). this accelerator begins to melt around 145°c and begins to decompose around 140°c. dpg decomposes into o-toluidine, ani-line and several other compounds. ani-line is presumed to be a potential car-

unveiling dpg rubber accelerator: features, applications
dpg (diphenyl guanidine) is a versatile rubber accelerator with notable characteristics, including medium-fast acceleration, moderate reactivity, good scorch safety, and excellent vulcanization properties. it finds widespread application in various rubber products, including tires, industrial rubber goods, and footwear.
curing characteristics, mechanical and thermal properties of,reclaimed rubber was cured using different types of vulcanization accelerators (mbt, tbbs, tmtd, dpg, cbs) commonly used in industry. two ratios of vulcanization accelerator/sulfur [2:1 as conventional system and 1:2 as effective system (ev)] were used.
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.
- 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.
- What is the role of DPG in a carbon black-filled rubber compound?
- The original task of DPG in a carbon black-filled rubber compound is the support of the crosslink reaction as a secondary accelerator. Its role in a silica-filled compound is much more manifold. An addition of 1,3-diphenylguanidine (DPG) in the early mixing stage enhances the silanization reaction as well as the filler-polymer coupling.
- What is the role of DPG in elastomers?
- TYPICAL ROLE OF DPG DPG (Fig. 1) is an aminic accelerator without sulfur. It is useful as an accelerator/activator for typical elastomers like NR and SBR. It activates accelerators such as 2-Mercaptobenzothiazole (MBT), 2, 2 -Dithiobis(Benzothiazole) (MBTS) and sulfenamides. For this, it requires the use of zinc oxide and fatty acids. [1,2] III.
- What is DPG used for?
- DPG requires the use of zinc oxide and fatty acids. DPG provides satisfactory processing safety and storage stability to rubber compounds. In light colored goods, it causes a brown discoloration and is not recommended for use in compounds that have contact with food (imparts bitter taste). For best aging results, an antioxidant is required.
